Stan Heya Stan,
Greets and welcome!
Well done on the open mic's and the upcoming gig - a open mic is something I've never quite managed to get around to doing - been far happier to hide behind a bass in a band than try and front a set.
We used to do a regular Gauteng jam session - lots of fun, but figuring out venues & schedules is always tricky. We.ve got a whatsapp group that's a bit more active than the forum - if you are interested, DM me for more details.
Good luck for the gig!
