You can record over the Doc Mock theme song or record a totally new one, just make sure you use the same original lyrics in your performance. Email all Youtube links to firstname.lastname@example.org and/or post them here in this blog thread.
This contest is ongoing and anybody who sends in an entry will have their song/video immortalized on a future live episode Doc Mock’s Movie Mausoleum. Enter as many times as you like and feel free to have your friends join in to sing with you in your performances! Looking forward to seeing what you guys can come up with!
