"BROADWAY LEGEND CHITA RIVERA IS IN TOP FORM AT BIRDLAND!" That’s what the pages of Variety screamed the day after she opened at Birdland! Chita is celebrating the release of her new solo album, "And Now I Swing," from new indie label Yellowsound. Onstage, she says that she’s been on Broadway since 1950, which means she's now entering her 60th year on the boards. That’s right…she’s 76, but you’d never know it from the high-energy razzle-dazzle she serves up in her 90-minute show. She has five more – and I think you better call the box office now (212.581.3080), unless you want to miss one of the best nightclub performances of the year. You’ll hear some fantastic material, including "Sweet Happy Life," Vincent Youmans' "More Than You Know," Jacques Brel's "Carousel," Carol Hall's "Circle of Friends," and three from Kander and Ebb, as well as medlies from "Bye Bye Birdie," "West Side Story" and "Kiss of the Spider Woman." Opening night was a Who’s Who of Showbiz Royalty, as evidenced by Steve Sorokoff’s photo (left). That’s Michael Douglas with Catherine Zeta Jones, whom Chita loved in “Chicago,” the movie. “You can keep the Oscar…I’ll keep my vamp,” she camped as the band bumped us all into “All That Jazz.” Musical-theater honor roll in the house included names like John Kander, Terrence McNally, Bebe Neuwirth, Alan Cumming, Brian Stokes Mitchell, Lucie Arnaz, George Dvorsky, Stephanie J. Block, Colleen Ballinger, David Hyde-Pierce, Lin-Manuel Miranda, Harvey Fierstein and Tommy Tune -- and those were only the ringside tables. It was a night none of us will ever forget.
