When we went to add the Bottle Dance in 82, we were looking for whatever little edge we could get over Concord for the finals. They pretty much kicked our butts all season, but we thought a little blast of GE might do the trick. We were taken away from our normal practice field to a high school in the suburbs of Montreal. We had been practicing on a beautiful field in the shadow of Olympic Stadium. It was all very secretive as we learned the music and drill. If I recall correctly, we learned this between prelims and finals, so we didn't have a lot of time to practice. The drill had the hornline spread across the front sideline, so it was very hard to see our drum major, Mike Zapanta. Once we started into the Bottle Dance, it was total chaos; the crowd was going nuts, and we couldn't even hear ourselves playing. In the end, I think the side one horns ended about a full second earlier than the side 2 horns. YIKES. Needless to say, Concord took it all home that night, and deservedly so.
I have been getting back into drum corps this last year after 20 years away from the activity (largely due to Tournament of Champions and my son starting marching band). I have been listening to the BD shows from 80 - 82. Holy crap, were those guys good!
