Wow maybe I am old, but for me when around 6 or 7, my father gave me a pile of 78 to play on my little toy record player, saying those one were mine (because he didn't about old RnR). I played them a lot, but he one that hook me on music, garage or not, was Little Richard "Keep A-knockin' ". Everything in that song was, for a young who couldn't understand english, totally insane. The beat, the voice, the energy, it puts a mark on my soul. Music can be totally out of control. Next time, the other song to have such an impact one me was the Ramones "Blitzkrieg Bop" at 11. That was it, at this age I have decided I will never follow mainstream boring music. Still on the same path since then.
Wow, I never thought of GG Allin in terms of power pop, but I'm amazed at how well it fits now that I'm looking at his music through that filter. It's easy to label him as punk because of the lyrics, leather, blahblahblah, but the MUSIC is totally power pop. Honestly, my mind is pretty blown right now.
Also, in response to the original post- you should watch the documentary Hated. It's good, plus it him playing this, one of my favorite songs of all time-
