One other person suggested this, but I have to second them. The Village People musical Can't Stop the Music starring Steve Guttenberg is one of the most deliriously terrible movies I've ever seen. It's also the movie Olivia Newton-John turned down to do Xanadu. Because XANADU seemed like a better bet. It's a blast. Very much in the Glitter, Burlesque, Xanadu, Liz & Dick category of campy gay delights.
