I've made two original song videos for Rocky Horror to the tune of "You Always Hurt the One You Love" by Spike Jones and "Tubular Boobular Joy" by Best Brains. Find them in my cast's RHPS site, LambdaPsiPhi.com.
And, if you like ReBoot, I have made a ton of ReBoot music videos. They're in my ReBoot site, Slack & Hash's Domain.
