Ya'll are making me feel old. I saw them in my amazing late 70s concert extravaganza. I forget all the bands. I saw PF on the Animals tour, Eagles on the Hotel California tour, Fleetwood Mac on Rumors, Led Zeppelin on Presence (but they played very little from it; they did their old stand bys), Kinks on Low Budget, I saw Lynyrd Skynyrd just a few months before the crash playing songs from Street Survivors (that one gives me chills), AC/DC on Highway to Hell and so many other bands - ELP, Yes, Aerosmith, Santana, Alvin Lee, Robin Trower, Foreigner, Bob Seger, Derringer and several more. I wish I could remember it all better...
