Maybe Fran can answer but read somewhere that Suns not so nice nickname was "Santa Flushing Vanguard" since they did more of a Jr style type of show. And of course Sr style = in your face. Just don't know when that nickname was used. 1977/1978 shows were similar with some of the same songs. Trying to remember what year they did a African rhythm type drum solo (right before 'Spain'). One of those WTF things that you thought they'd go more into corps style at the end but... nope. That kida defined their style for me.
Larry at Bucknell show when Cru was whipping the crap out of the guy and the crowd was sitting with their mouths open in shock. "You think we're tough when you're late for practice. Rochester whips you".
I remember my dad's reaction:
"I've been watching drum corps since 1962. I have now seen it all"
