Nice post, John.
When I was in the 8th grade, NOW we are talkin prime Teenage boy hormone filled rock n roll magnet to steel scenario and the rest is history. 1978-79 and it was like a whirlwind of all the new experiences like Van Halen, Alice Cooper, Ted Nugent, Def Lep, Stones, Zep, AC DC, Maiden, Rush etc. I seem to remember 2 happenings in the halls of middle school. Both centered around concerts my buddies got to go to. Def Lep during the High n Dry time, and Rush right around 2112 time. After buying 2112 really by chance pick out of about 4-6 different Rush albums, I just say it was dumb luck. Shortly after I had an older neighbor who had a 3 disc set of RUSH, Caress and Fly by Night called Archives. Then I got Farewell to Kings, Hemispheres, and Perm Waves, Moving Pics and All the World's a Stage. Needless to say, I was hooked.
Same thing went for UFO. If I like a group, they pretty much permeate my being.
