I've just learned "I'm Tore Down" as done by Clapton, and Mary Had a Little Lamb by SRV, and I'd like some more suggestions for bluesy songs to learn. Don't say Pride and Joy, or you will feel my prickly wrath. Or just be ignored by me, one or the other.

Any help would be appreciated, though, as I'm always unable to figure out what to learn next, and have a very small repertoire to pull out when I'm practicing.
