Amanda Palmer released en EP last year called Amanda Palmer Performs the Popular Hits of Radiohead On Her Magical Ukulele.. which is pretty long. The longest one I know though is by the lovely Fiona Apple
When the pawn hits the conflicts he thinks like a king
What he knows throws the blows when he goes to the fight
And he'll win the whole thing 'fore he enters the ring
There's no body to batter when your mind is your might
So when you go solo, you hold your own hand
And remember that depth is the greatest of heights
And if you know where you stand, then you know where to land
And if you fall it won't matter, cause you'll know that you're right
Often just referred to as When the Pawn..., but that's the full title
