On promo: No
Date: April 1 (Saturday). In the picture below (of the list for the 1st day) there’s a sign for him. Not sure about the other times he played (per what he says below).
“I knew the promoters and some of the LA crew (Lew Weinstock, Steve Wheeler etc) and did a solo set (acoustic guitar and sang) in between acts throughout the festival. Love your Mar-Y-Sol website!
