I found another version of this great song done by K T Tunstall. As many readers pointed out the last time I posted this, that this song has a few similarities to Howling Wolf. I can sort of hear it in the whoo hoos, but it is certainly an original song. Plus how she can play that live is pretty incredible. I watched her do it on Letterman one night, and she had a foot pedal that repeated what she did. Pretty cool!!!
