Brilliant Mistake, a one-night-only concert, brought together many Broadway stars to sing the music of rocker Elvis Costello. Costello, a Rock & Roll Hall of Fame inductee and a Grammy Award-winning singer/songwriter, joined the stage celebs at the Gerald W. Lynch Theatre at John Jay College. The event raised proceeds for Friends in Deed, the crisis center for people with HIV/AIDS as well as their family and friends. Take a look at your favorite theater people (some in fun Halloween costumes) and the uber-talented Costello.
