Musicals about the Movies

This morning, driving into work, I was listening to the 1964 musical Fade Out, Fade In, which was a Carol Burnett vehicle right after Once Upon a Mattress. The musical is based in the 1930s, and is about an aspiring starlet. This got me thinking into what musicals have been written about the movie industry. I could think of the following, in no particular order:

Bricusse/Newley: Chaplin (closed before Broadway)
Herman: Mack and Mabel
Herman and others: A Day in Hollywood, A Night in the Ukraine
Styne/Comden-Green: Fade Out, Fade In
Webber: Sunset Boulevard
Coleman/Zipple: City of Angels

Are there others? I couldn’t think of any others, in particular, any by Bock/Harnick.
