Hey Hey by Big Bill Broonzy as covered by Eric Clapton on his unplugged album.

It takes a bit of practice to get the thumb going but the rhythm is pretty straight forward and once you lock into it then it's a lot of fun to play. just break it down into bars and practice it slowly. It's not too difficult and it sounds great.

Also...this should go in MTs only suggest me a song thread. Which is why I closed it.
