The American Film Institute (AFI) revealed the top movie songs of all time in AFI's 100 Years... 100 Songs three-hour special television event hosted by John Travolta. Having contributed to the list himself-his dance moves helped SATURDAY NIGHT FEVER'S Stayin' Alive disco its way into a Top 10 spot and he made his own way onto the final list with his performance of GREASE'S Summer Nights-Travolta was a natural representative for 100 years of American movie music.
