I was there. A buddy of mine named Tom Witt got four tickets and was kind enough to hook me up. We were seniors in high school and drove over from Carmichael (Sacramento). The chance to see The Who with the original line-up in what was formerly an ice skating rink was phenomenal. All of the craziness up close. It must have been our lucky night because we got pulled over on the way home and were let off the hook!
This was a great era for SF concert going as I saw many bands at Winterland over the late '70's including The Ramones, The Jam, The Tubes, Springsteen and the E Street Band (Darkness On The Edge of Town Tour, "Let's go, I hear this guy is good live" LOL), Bad Company and the Sex Pistols. I believe the ticket to the Sex Pistols "Never Mind The Bollocks" tour was something like $3.50!
