First, here's the 1978 Santa Clara Vanguard with their guard dancing around a maypole.
Insert joke about them wearing red, playing Soviet-era music (Aram Khachaturian's "Gopak"), and being the vanguard of the protelariat here.*
Next, the 1979 Schaumberg Guardsmen doing their version of a maypole dance, this time to something more in tune with the tradition, "Greensleeves." First, two color photos.
Now, another, larger photo.
With that, I wish you all a happy May Day!
*The Vanguard actually was a working-class organization at the time, so the joke is more apt than one might think. The ex-girlfriend I mention here from time to time marched in them from 1977-1979--in fact, she may be in the photo--came from a working-class family and described how most of her fellow corps members shared her background.
