Before taking the Radio City Music Hall stage as a Tony Award presenter on Sunday, former American Idol judge and pop star Paula Abdul got in the Broadway mood by taking in a hit show. With her former Idol protégés Diana DeGarmo (Season 3) and Ace Young (Season 5) currently leading the tribe of the Tony-winning Hair revival over at the Al Hirschfield Theatre, naturally Abdul joined in for the nightly be-in at the show's 500th performance on June 11.
