Y-Chromo rehearsed for his high school's production of GREASE. He played "Doody", which was a much larger role in the stage version than in the movie version. According to Wikipedia: Several musical numbers were not used in the film. They appear, however, as "Jukebox" tunes, or band numbers at the high school dance. Among them: ..."Those Magic Changes"... which [was] performed by characters in the stage musical (however, Danny does sing along with the band for a few lines of "Those Magic Changes"; on Broadway, John Travolta's character Doodie [sic] sang the song). And in between the Friday night show and the Saturday night show, Y-Chromo marched in the local St. Patrick's Day Parade. where his high school marching band took gold. Call me Mom-the-Taxi.
