Growing up in the mid '60s, I never gave much creedence to most of the '50s and early '60s artist. I did love Chuck Berry, but Elvis, JLL, all the surfing stuff, it never did it for me. My world opened up when the Beatles arrived.
Anyway, many years ago I got the LaserDisc (!!) of 'Great Balls of Fire', with Dennis Quaid playing JLL. I thought it was great. The music was great, and the first half of the movie is classic. It kinda got weird when he went to Europe, but after seeing that movie I had a much deeper appreciation of him and his catalog.
I also was kinda partial to his version of Pink Cadillac that he did with it's writer Bruce Springsteen when he released the album "Last Man Standing.
RIP to a great piano player, artist, and one heck of a wild man!
