Tonight at the American Airlines Theatre, tons of Broadway notables will be getting together for the third installment of Broadway Backwards. The Broadway Backwards concerts put a new spin on Broadway showtunes by letting men sing songs originally written for women, and by having women sing tunes traditionally sung by men. Among the Broadway performers on the bill tonight are Gary Beach, Cheyenne Jackson, Liz Callaway, Anthony Rapp, Len Cariou, Ann Harada, Brooks Ashmanskas, Sierra Boggess, Tituss Burgess, Charles Busch, Kerry Butler, Jenn Colella, Gavin Creel, Sandy Duncan, Malcolm Gets, Neil Patrick Harris, Jose Llana, and Lea Michele. Seth Rudetsky, who was recently featured in the Broadway revival of The Ritz, will host the event.
