I quite like the idea of a session where you have access to a microphone but phone up in advance and book yourself without the need for an audition. There's one starting up in Sidmouth soon.

I find with the truly open mic nights I've been too (which may not be representative), often the guys with the loud voices and guitars take over and any one slightly mild mannered (or female and unaccompanied - yes me too Carol) feels unable to have a go. You don't feel you want to change the tempo of the night. Mind you, I've got better at just standing up and barging my way in. Why let THEM have all the fun?!!
