That was a highly influential song for me, for a while as a teenager it was my favorite song.
Not just the song, but the video clip. The animated marching hammers. I was a young kid when that song was around for the first time on the radio and on the TV, in the early 80s. It was really unlike any of the other music around at the time, and there was something about it that grabbed my attention. Probably the overt rebelliousness of it. The local high school had an art display based on the Wall album. I saw it frequently because the local library for my area was in the school. Just to put this in further context, I'm talking about Australia, suburbs of Melbourne, around 1981. They made these big foam puppets of the teacher and the hammers and the things from that video clip. And it was the perfect setting for it, because it was a very grey dreary-looking high-school with endless rows of lockers. So that song stayed in my memory, but I didn't re-connect with it until years later, when some friends at high school gave me some Pink Floyd tapes and I became a Pink Floyd fan.
I adore that song, and I treasure having seen Roger Waters perform it live. I became a guitarist, and Dave Gilmour was definitely a primary influence on me. That guitar solo he does at the end of "Another Brick in the Wall (part II)", is so contextually perfect, and so unique, to me it is one of the finest examples in existence of what a guitar can do in terms of expression.
