I've decided to try and structure the news about Waits covers a bit. So, from now on, you should find a round-up of all new covers I'm aware of every last day of the month. Should you find any covers yourself, you are more than welcome to let me know.
Robert Plant and Alison Krauss cover Trampled rose on their album Raising sand
Guy Davis covers Midnight lullaby on Down at the sea hotel (by various artists)
Note: seeing as the name Coverville has already been taken, I've decided to call this The Boulevard of Broken Covers.
