Man, I saw Warren Zevon on Letterman about 7 years ago. I don't remember much about the actual performance at the moment, but I'm sure I have it on tape somewhere. Tom Waits, on the other hand, I know about.
I haven't listened to anything on 'Alice', but for the sake of conversation, I'll take a look at it. You can't go wrong w/ Waits anyhow.
His story/song "Big Bad John" was pretty huge in the early 60s, and it was the subject of endless parodies and a TV movie. It's even been covered by Johnny Cash. "At the bottom of this mine lies a big, big man."
