This will take you to his website for his blues/boogie bar/lounge in San Franciso, the BoomBoom Room. The opening page has a great graphic of him.This one will take you to a discussion thread we recently had for JLH's 82nd birthday, which you might find interesting.
Hope this helps. Have you thought of making a videotape, too? Sounds like the kid is doing great.
All the best,
