Bill Graham on stage with Santana Edit The photo with Bill Graham is interesting! I wouldn't give him the musician credits because he really wasn't an official member. I'm not even sure if this is a cowbell. Any more details on this topic? Markus (talk) 08:00, January 25, 2017 (UTC) Retrieved from "http://woodstock.wikia.com/wiki/Talk:Santana?oldid=6401"
