Hi Frank. I hate to provide any correction to your excellent list, but Fillmore East was in NY. So the more appropriate SF concert choices would be:
Fillmore West vs Winterland, or Avalon Ballroom vs Fillmore Auditorium vs Longshoremen's Hall.
A couple of others I thought of are:
Converse vs US Keds, and Hightops vs Lowtops.
KMPX vs KSAN (on FM radio).
Levis vs Lee jeans vs Wranglers, and straight-leg vs flairs.
