We didn't play much jazz. Mostly country area so lighter rock was about it for pep band. A large portion of the adults were still only country music listeners.
If you were in band you were pep band. Games were treated like concerts. Only football or basketball players were exempt. I think the hardest song for me was the "Peter Gunn Theme". My fingers are really too short to do it easily. Teacher had me practice on the double bass until I could pull off the contortions that required of me at speed. Made the electric bass easy in comparison.
I liked "25 or 6 to 4". Felt it was fun, though easy. Very recognizable bass line though. I loved that the first year I played. It starts with the bass. At basketball games we'd start playing it when the guys teams came out and players on the other team would miss their warm up shots sometimes when they realized it was a girl playing it. Something unheard of in that area.
