David Foster had plenty of support at the opening night of BOOP! The Musical. The sixteen-time Grammy Award-winner has written original songs for the new Broadway comedy, which brings animator Max Fleischer's iconic cartoon character Betty Boop to the stage. It's the first time he's ever composed a stage musical — a milestone worth celebrating in the hitmaker's five-decade career. So it's no surprise that David was surrounded with family on Saturday, April 5, as BOOP! officially debuted at the Broadhurst Theatre in New York City.
