I've watched this movie everyday since Sunday! I love it!!
Hard to pick favorites, but I think I have to go with "Eddie's Teddy". I like Professor Scott's little dancing thing he did. Cracks me up. And "Planet Schmanet Janet" is great, too. Of course, "The Time Warp" is awesome. Gosh, I love Richard O'Brien's voice, especially his little part in "Over at the Frankenstein Place".
"Sword of Damocles" is great, as well! I always get the urge to stand up and start dancing the way Riff Raff, Magenta, and Columbia do.
As I think about it, my favorite may just be "I'm Going Home". So wonderfully sad.
But, all the songs are great!
