I went to the Getaway Pub for jam night and it was like one of those nightmares you have where you are on stage, but you have no idea what you are doing. No bass player showed up, so I played bass all night. People were calling out songs I never heard of, let alone knew how to play. Thank goodness I can watch guitar players and follow the basic chord structure. And 16 bar blues walking bass patterns are a snap. But when I had to play Queen and Rage Against the Machine, well lets just say that was more interesting than good.
The most often used keys last night were A Blues, E minor and G Major.
The most fun is when me, a guitar player and a drummer spontaneously played Maggot Brain by P-Funk. The worst was when the Country Western Git-Fiddle player decided to join us in Maggot Brain. I don't believe it was ever meant to have a twangy Telecaster! Heh.
We also had a hammer dulcimer player who was kicking out some serious folk jams.
