Amazingly enough I've never seen Brigadoon. I'll have to put that one on my list.

I actually love Singing in the Rain, moreso for Debbie Reynolds (I saw her do Unsinkable Molly Brown live here in Houston and have been a big fan ever since), then Gene Kelly, although I do love his classic dance in the Rain. I also love Donald O'Connors "Make'em Laugh" dance routine too.
