His father and Anna were already in their seats, looking slightly frumpy in the younger crowd. Why such a public meeting, where everyone could see? Or was this part of the plan too, something that could be verified later? Anna was friendly, pleased to see them, but his father seemed preoccupied, as if he already regretted having come, bothered by the noise. When the lights blinked on and off, no one paid any attention, still talking in the aisles. Then the curtains opened on the band playing ‘Let’s Dance’ and there was a roar of recognition applause and a scrambling for seats. An emcee appeared at the mike, speaking Czech, then Benny in English saying how happy he was to be here, then the opening notes of ‘Don’t Be That Way’, more applause, and the evening, in this unlikely place, began to swing.

The music was wonderful. It was the standard program–next the ‘King Porter Stomp’–but the audience made it seem fresh, their enthusiasm flowing up to the band with such force that Nick saw some of the sidemen grin, bending into their instruments to send it back. “You Turned the Tables on Me‘, with its funny, innocent lyrics. How many of them knew what the words meant? But the music, just as they always said, was its own language, and the audience was answering it, some actually tapping their feet, squirming in their seats to the beat. Nick thought they might leap up to dance, and he saw that in the back of the hall, where the bar was, some of them had. Upstairs in the ring of boxes there were men in bulky suits, Party bureaucrats, their wives fat and shining with costume jewelry, but the crowd on the floor ignored them. There were no uniforms anywhere. Just the music, an official time-out. ”Elmer’s Tune’, where the gander meandered. American music, the happiness of it, as much a part of him as childhood stories. He smiled at Molly, who was drumming her fingers.

When Goodman started the clarinet lick of ‘When It’s Sleepy Time Down South’, the notes jetting out like liquid, he turned to his father. Nick expected to see his face soft with nostalgia, but it was cramped, white, and he realized that his father hadn’t been preoccupied but worried. Even the music couldn’t reach him, wherever he was. Nick looked at him for a second, wondering what was wrong, then made himself turn back. Don’t ruin it. He’d find out later. Now they were here, not in some troubled past, not even anymore in Prague.

There was an intermission after ‘Avalon’ and he went with Molly to the bar, his father staying behind, sitting it out. The lobby was filled with smoke and spilled beer, and the crowd was even more energetic than before, loud with drink. It took a while to get the beers, then a few more minutes to find Molly. She was standing near the door, her back to him, talking to someone. For a moment Nick hesitated. Jiří again? Then she moved slightly and he saw that it was Marty Bielak. Why not? It was his music too.

“Hello,” Bielak said. “Enjoying it?”

I was, Nick wanted to say, but just nodded, handing Molly her glass.

“Of course, I remember the Meadowbrook,” Bielak said. “Before your time. Helen Ward was the vocalist then. And the Long Island Casino. That was something.”

Nick tried to imagine him young, skinny, with a date by the bandstand, raring to go.

“The good old days,” Nick said.

Bielak glanced at him. “Well, the music was good. Maybe not the days.” And then, wanting to be pleasant, “It was another time. Everybody danced. It was always dance music, you know. Not for sitting. To think I’d be here in a concert hall—”

“In Prague,” Nick finished.

“Yes, in Prague. But the music doesn’t change.”

The lights flashed, the signal to return.

“Well, it’s good you could come,” Bielak said. “A taste of home, eh?”

Did he really think this is what they still danced to? An exile’s memory, stopped in time. Nick saw his father suddenly, walking down streets he thought he knew, amazed at buildings that shouldn’t be there.

“They seem to like it,” Nick said, nodding to the crowd.

“What’s not to like? Well, it’s that time.” He tossed back his drink.

He seemed to be waiting for them, but when Nick said, “We’ll just finish these,” he nodded and said, “Enjoy. I’d better get back upstairs. I don’t want to miss anything.”

“You’re in a box?” Nick said involuntarily. With the Party men. A bird’s-eye view, to look over the crowd.

Bielak smiled weakly. “No, higher. The cheap seats.” He moved toward the stairs.

“C’mon,” Molly said, “they’re starting.”

“No. I don’t want him to see us.” A legman. “Wait a minute.”

The crowd had started yelling and clapping, and Nick heard the opening drums of “Sing, Sing, Sing.”

“What’s the matter?”

“Don’t you think it’s funny, his running into us like that?”

“Maybe. Anyway, he has seen us, so what’s the difference? Come on.”

But he held back. Were their seats visible from the balcony? “Not yet. Give it a minute.”

“Okay. So what’s our cover?” she said mischievously. “Want to dance? Can you?”

“Can you?”

“In this crowd?” She laughed, and Nick took in the couples around them, exuberant but awkward, as if they had picked up the steps from old movies.

“Chicken,” she said, leaning into him. On the stage, the brass section stood up, horns blaring, infectious.

“Say that again.”

“Chicken,” she said, putting her hand in his to start the movement. And then suddenly he didn’t care who was there and he swung her out and they were dancing, his arm reaching over to turn her around, then lead her back, laughing at the surprise in her face. How many years had it been? You’ll never know when it will come in handy, his mother had said. Mrs Pritchard’s class, an agony on Tuesday nights. The girls tall, in flats to mitigate their growth spurts, the boys resentful, shirts never quite tucked in. When am I ever going to have to know the rumba? On boats, darling, she’d said. They dance on boats. And the lindy, another generation’s dance, learned step by step but now, like riding a bicycle, all familiar and fluid, so that he could do it fast, Molly trying to follow, arm over, then back, finally come in handy, here of all places.

He felt the heat in his face when the drum solo began, but Molly was smiling at him, excited, and they kept up with each other now, the pleasure of the movement like a kind of foreplay that made everything else disappear. He noticed vaguely that people had made space around them, watching and stamping their feet, but he kept his eyes fixed on her. The song started its false diminuendo, everything running down and building at the same time, and they danced close, keeping pace, waiting for the break. Sweating. “Wow,” she said, laughing, panting a little. “No, you,” he said, meaning it, because he didn’t dance, not like this. Then it came, the sudden loud blast of the finale, irresistible, and they were dancing wildly, grasping hands to hold on, their circle of movement spinning wider to fit the music, until the dramatic up-tempo crash, the real climax, and they hung on to each other, winded, while the entire hall shook with applause. Goodman’s crowd-pleaser, the same frenzy.

The applause was for the band, not for them, but he heard it like an alarm clock, bringing him back. They were supposed to be inconspicuous, not drawing a crowd. He dragged Molly outside the circle of people and stood for a minute against the wall, catching his breath.

“Who would have thought?” she said, smiling, hanging on to him. She reached up and wiped his temple, smoothing back the damp hair.

“We’d better get back,” he said, but when he looked up he saw that his father had come to find them and was standing there watching. He felt embarrassed, as if they’d been caught necking. Molly followed his gaze and turned.

“Did you see?” she said to his father, still smiling.

“A killer-diller,” his father said wryly. “We were wondering what had happened to you.”
