How do I join my first jam.without panicking? Im not sure ill remember any songs. Plus my song repertoire is pretty limited. Should I just try to vamp ? Maybe do forward backward rolls over chords.?. Last time I played my instructor tried to vamp behind me amd I was totally lost. 
First jam jitters
