Bands and Live Performances I've been a part of:

#3.

During my sophomore-year of High School I played in the "Folk-Club".  After our first performance at the Junior High School, we were also able to play for our classmates at the High School itself.

In addition to the previously listed "Best of My Love", "Stairway to Heaven" and "Smoke on the Water" from the Junior High performance, I know I was a part of a trio attempting a couple of songs by the band Rush (who and which I had never heard).  

Only knowing the chords and notes being played by the guitarist by watching and listening, I improvised (faked) my way through on bass.  It had to have been brutal for anyone listening with a knowledge of the orginal songs.  Still, not being afraid is important in adventures.
