"Fumbling With The Blues" by Tom Waits.
Actually, Tom Waits did a number of songs that would translate well- "Jersey Girl" would be another good one, as would "The Heart of Saturday Night". Also "New Coat Of Paint".

I used to get good results playing Melissa Etheridge's "Don't You Need". Pink Floyd's "Granchester Meadows" is unusual and very pretty.

If you're looking for something lighter, try some Tom Lehrer. "Poisoning Pigeons In The Park" is easy and gets them fast, "Pollution" works well, "The Irish Ballad" is simple to play... yet no one ever sings them.
