You should (and likely do) recall David Lee Roth's "Running With The Devil" isolated vocal track and the mashups it inspired. Offering a new dose of a cappella gymnastics, there's a Diamond Dave stream circulating. This time he's giving 1984's "Hot For Teacher" his all (which it turns out is a lot). He's joined by Eddie and Michael Anthony (and Alex?), a wall of reverb, assorted sound effects, and more words ("I don't feel tardy")/less grunts.
