Here's a rare, 1967 glimpse of EL_ULY's first public appearance. Apparently, his first gig was for a cereal commercial that never aired, but his second gig was an internal IBM video.

If the video is as factual as I believe it is, that coffee machine really messed with his insides. I mean, he lost all his teeth. No wonder he had to switch to rice crackers during performances, poor guy.
