From 11-year-old jazz trumpet player Geoff Gallante, who played and crooned "Bare Necessities," Vegas and Café Carlyle headliner Clint Holmes, Irish TV's "Fame: The Musical" Finalist Michael Joseph, cabaret star KT Sullivan, jazz-man Marcus Goldhaber and "Beauty And The Geek" star Richard Rubin, who stormed through "Maple Leaf Rag" with a bag on his head, the "extreme open mic" entertained the packed house into the wee hours. Host Jim Caruso, as well as the visiting talent, were accompanied by the Cast Party Symphony Orchestra (Tedd Firth, Steve Doyle and Carmen Intorre). Jim Caruso's Cast Party takes place at Birdland (315 West 44 Street) every Monday night at 9:30.
