A song you know all the words to.
Damn, I've already done Bat Out Of Hell... Oh, I know. The Smiths - Heaven Knows I'm Miserable Now! Best sung in horn voice. If you don't know what that is, tell me and I'll give you a demonstration. Maybe.
In fact, if I get 10 comments on this post requesting a horn voice vlog, I'll make one for you. How's that for a bargain?
