Has anyone noticed that Red House by Jimi Hendrix and Texas Flood by Stevie Ray Vaughan sound an awful lot alike?

I was just wondering if anyone knew why. Is Texas Flood actually a cover or did Stevie plagerize the song?

Oh, and which one do you prefer? :P
texas flood is a cover by SRV. and yeah theyre similar, because theres only so much you can do with the blues. i prefer red house, but not the hendrix version - theres a guy at my local blues jam who does the best cover ever, its seriously intimidating to play with him lol.
