Random Photo Fridays - Hit song formula

So far I only have Mondays covered with a little vintage photo love... So today in an aim to regularly post images to my website etc I thought would start with a little Random Photo Friday find from my archive (e.g. a hard drive full of images that have never seen the light of day)... Titled 'Hit Song Formula' - for obvious reasons.... *parental warning contains swear words.... This image was taken last year at a rehearsal studio in North Melbourne....
