Singer Ann Hampton Callaway called it 'Musical Church,' and deemed host Jim Caruso the 'Irreverent Reverend!' Monday night's Cast Party was the be-all and end-all of extreme open-mic madness, with impromptu performances by some of the best and brightest on the Broadway, jazz, cabaret and concert scenes. Callaway led a blues vocal quintet, along with headliner Lorna Luft, Broadway leading lady Carrie Manolakos, Birdland's William Blake and Manilow-co-star Muffy Hendrix.
