Veteran southern California psychedelic rock band Iron Butterfly, best known for their massive 1968 hit "In-A-Gadda-Da-Vida," is coming to the Coach House in San Juan Capistrano on Friday, July 3. $15 tickets are already on sale. This isn't normally the type of show we'd dedicate too much space on here to, but any excuse to post this video is a good one. I had totally forgotten that this scene was the origin of "rock and/or roll." (Though why it's inverted, I dunno. Maybe whoever put it up thought it would be less likely to get taken down that way? Also, notice that this episode was written by The Office showrunner Greg Daniels!)
