In '79 and '80 the crowds at Allentown would chant "EAST EAST EAST!' It came off to me as a mix of support for Cadets/27 and hoping that BD wouldn't win again (which we didn't always do there at that time)
That would be an awesome show although maybe a bit too self-referential, given all the other evidence presented in this thread. Probably a good thing you explained it too.
