Cream
My music promoter cousin hooked me up as Ginger Baker's videographer for his jazz band in the 90's. I had ZERO clue who he or Cream was and couldn't name a single song. I got to know him and his (then) wife Karen over a couple years. I look back at that and just shake my head at how ignorant I was of his legendary status. Maybe that's why he liked me. To me, it's now like being buddies with Mick Jagger only to find out who he really was, decades later. Such a waste.
