Mystery Band??

I need help tracing this Perth band circa 1969/1970/1971. That's a young Mick Cater recording them at a hall at the Civilian Mamed & Limbless Association cnr Murray St and Havelock St. Mick can only remember the lead singers name which is possibly John. Anyone out there recognize the pic. Let me know.

Date: Feb 2011. Okay I just got confirmation that the guitarist on the far right is Ross Adams. thanks to Syd Nagel for spotting this.
