I don't remember them, were they a Margs band?
I remember the 10c Shooters...one of the members lived across the lane from us running behind Railway Trc. He sold guitar strings & made very nice accoustic guitars.
A friend & I used to Jam with a few people accousticly. We had a jam night down at the cafe/food joint over the road from settlers for a while. I think it was the Pumphouse cafe, had an ancient fuel bowser out the front like Gracetown, but the buildings gone now. But yeah got too popular/big & managment closed it down. They didn't mind a couple of accoustic guitars, but once it got too the point of 3 or 4 bongo drummers in the mix it was GG I like to blame them, not my singing lol

Standout bands I remember;
Beaverloop
Fireballs
Shihad ( but as Pacifier - changed name for awhile coz sounded too much like Jihad)
Rebeccas Empire
Tumbleweed
Cordrazine
But I'm a little embarrassed how little I remember in regards to bands, just remember a lot of great bands we heard on JJJ would do the Settlers Thurs before playing Perth. Reminds me of this convo a couple of young blokes were having in the surf last week. One guys was like telling a story of a big night out & his mate replys, YEAH I was there with you...LOL...I was that guy
