That's Dancing! 2007

Minnelli, whose South American and European tours this year have received critical praise, says that the Thompson concert is one of the most challenging — and rewarding — of her career. “Musically, it’s really demanding,” she says. “And dance-wise, I haven’t danced this hard since Liza With a Z. When I’m not performing or dancing for eight hours a day [during rehearsal], I’m in dance class. I’ve always taken a two-hour dance class a day my entire life.”
