The People's Open Mic is at the Goldhawk every Tuesday Night. It's a fun night with lots of local bans, musicians, poets and creative types in general.
The Open Mic starts at 8PM and can go on until 11PM. I will be there with some friends and I anyone is welcome to join the fun. There is no cover charge to enter.
