Let the rehearsals begin for Neil Patrick Harris, who's starring in Broadway's Hedwig and the Angry Inch this spring. "Today was our first music rehearsal with the band," he told Vulture last night, at the Drama League's annual gala, held in his honor. "They’re a rock band ... Tits of Clay. We don’t fuck around." (Here's Tits of Clay getting introduced on the musical's Facebook page.) Harris plays the title character, a transgender rock musician originated by John Cameron Mitchell, who also wrote the book for the show. "I’m doing all kinds of prep," Harris told us. "I’m studying Bowie and Iggy and Lou and Tina. I’m working; I’m dancing around in heels for hours, and wigs, and changing my posture and losing weight." His quads are okay, he assured us, but "it’s a lot of flection. I’m used to standing kind of in stasis more, but I’m realizing now that women in heels stand at attention a lot more than guys do. I’ve got to stick my tits out a lot." Tits of clay? "They'll be tomatoes, but similar," he says. "You’ll have to come and see."
