Q: What song reminds you most of your school-days?

My little boy had his first day in school this week, and I was as excited as he was walking into this big building with all the older kids crowding around us. The little groups, the bikes, the ipods and PSPs, the chatter. To make it relevant here: which track would I associate most with my school-days?
Actually, two came to mind. One was Sniff 'n' the Tears's Driver's Seat, which for me will eternally symbolize standing in dark corners on school dances and hoping no-one will notice (and which I will mercifully no include here). And the second was Iron Butterfly's In-A-Gadda-Da-Vida. I specifically remember three days of religious orientation in some North German hicktown, sitting in a black-outed vicary basement with incense and berry-tea and rewinding the tape (which some guy had taken from his older brother) over and over again to take in the epiphanous 17 minutes of this. The drum solo. The organ solo. The closest we ever got to smoking weed.
When I listened to it again (to return to the awkward age) here at work, my co-worker turned around and told me that it reminded her of her long lost brother. So, Carlos, if you're out there in Guanajuato, call home, your mother is dying.
