World of Weird Al Yankovic

If i'm not getting off topic, this might be important. Does any body know this was played before Belvedere crusin? I was looking at Dr. D shows on some webssite and their were at least 1 or 2 shows before belvedere crusin's first air play. I like SCHOOL CAFETERIA, I have only eatin in a school cafeteria once and I can't remember it very well. Hey, Does anyone know were I can find those songs he did live on Dr. D's show? AKA Food Medley, School Cafeteria, and My Bologna?

I have the bedroom version, (the best one!) and the live version (the best quality). They are both hilarious, and I think one of the few of his early songs that could've been released.
