A great little animated story about why J.J. Cale never became a superstar, even though some of his songs did. cgod - you might like this. I know you're a fan.
When I first met my father in law (not yet my father in law) he and I immediately connected over classic rock. He mentioned the groups he loved, Zeppelin, The Allman Brothers and Lynyrd Skynyrd (he's southern). The one person he liked the most though was JJ Cale. He gave me some JJ Cales CD's and I really enjoyed them. His music is/was great and will forever remind me of meeting my father in law for the first time.
