Kristoffer Tabori is wrongly credited.
He's not a dancer as far as I know. Instead, he is one of the hippie/flower children at the end. I know because I've been a fan since seeing him in "Truman Capote's The Glass House"I recall seeing "Sweet Charity" on one of the movie channels and being stunned when I heard his voice.
I'd try to get this error changed, only I haven't had much luck doing things like that at IMDb.
