This one's from my high school years, and specifically around the time that I started playing the guitar. Actually, the song came out before I even had a guitar of my own, but once I did have a guitar and had formed a "band" — at that point, we were only a duo, really — I used the chord progression as inspiration for one of the songs of my own band (with lyrics written by the other guy).
Note: This is not the original recording as it appeared on their 1978 album, but a re-recorded version. The overall sound is a bit sharper, and Tommy's guitar solo here is also somewhat different from his original solo.
