Okay, talked to my husband and I got it wrong (he is an even BIGGER Weird Al fan). He DID ask for permission for most of his songs. He got it from Coolio's managers, but they didn't ask the artist himself.
I thought he usually asked permission. Almost all artists have been willing to give it. One notable exception - the little purple guy (Prince) wouldn't give permission.

That guy looks vaguely familiar. Can't put a name to the face though. Judging from what he is wearing, I reckon he is either a graduate, honorary graduate, or speaker at a graduation, but that hat ain't a normal graduation hat.
Must be a European graduation hat.
