Well based on replies to the thread there's 6 possible participants. I guess we won't need to hire out Suncorp Stadium!
A large rehearsal room might be the go, unless numbers increase radically. I know we have a couple of bass players in the mix, how about drummers? If not, I might be able to wrangle one in just for a jam.
Oh, and what about singers? I sing pretty well, but not looking to be the "lead singer" here. Plus my voice may not suit all songs/genres.
Music-wise I'm sure there's some common ground within the veins of blues and classic rock stuff. Easy enough to fill up a few hours (or more). Of course that can ironed out if/when we get to the point of setting a date.
I'll try and bump this thread along from time to time to keep us all interested.
