In September of 2000 I got the chance to see, hear, and briefly visit with the Reverend Patrick Henderson in Louisville, KY.  Who is Patrick Henderson?  Well dig out your Leon Live CD/album and listen to the piano at the album's start.  That ain't Leon, it's Reverend Henderson!  I got to tell Patrick when I saw him that he had "disillusioned" me in regards to Leon's piano playing. While that comment was in jest, it was meant as a compliment, too.  There aren't too many piano players who can share the stage with Leon in any equitable capacity. Patrick is one of those very talented few! IMHO.
