I saw Leon Russell in concert in an outdoor amphitheatre venue back in the very late '70's, opening for Willie Nelson. He was sooo good. I remember bits and pieces of it vividly.
Come to think of it, it may have been my very first concert on my own, unaccompanied by parent or guardian! LOL... Yeah, I think it was.

RIP Leon.

This has been a tough year. Sigh...
