I know that Hendrix covered it, an it rocks. https://www.youtube.com/watch?v=V-hmypa3wuA
I did not know Clapton did, and it is really good as well. https://www.youtube.com/watch?v=3KvtbZzx1xs
It is a shame though, I looked for a Stevie Ray Vaughn cover of it, but could not find one. I bet that would have been amazing.
Edit: And yes, I have heard Ray Charles's cover and that is fantastic as well. I was around when he did that
