Ahhhhhh yes...and I DID forget two of my other favorites...
1974 Kingsmen
1974 Muchachos
I think 1973 through 1976 were the top years of Drum Corps...:)
Yes, Muchachos...wasn’t marching over-aged members their downfall? 1975, I think.
Other favorites from the 70s: Troopers, Des Plaines Vanguard and Blue Rock.
