Here at CTYI in Dublin, a history of the American Pie tradition is being compiled. Yes, it's here as well. Anywho, we have a basic outline of how the tradition came about, but if you have any information as to its history it would be greatly appreciated if you shared it with us. Information on the chant (DIE DIE DIE DIE LIVE LIVE LIVE LIVE SEX SEX SEX SEX MORE MORE MORE MORE) is needed especially. Please refrain from sharing little stories that start with "this one time..." that took place within the last 5 years between you and your friends. We're trying to find out how this tradition started and its early history.
What we have so far: It was played last at the first CTY dance of the first CTY, which took place in the 70s when American Pie was in the charts. It was requested at subsequent dances, so its being played became a tradition. Certain elements of the tradition that go along with the lyrics are more or less self-explanatory (kicking off shoes, screaming, etc.), but we don't have a definitive origin for the chant yet.
In addition, origin stories for any other traditions are more than welcome.
