I saw these three in King St, Newtown, Australia, where I live. There was something about this beautiful girl, hair blowing in the wind, pulling a shopping cart with a guitar amp in it, that was mysterious and heroic.
Was she helping her boyfriend, or is she in the band? The guy on the left looks like a long-suffering bass player or drummer. The guy on the right, I imagined, was a cocky guitarist or singer.
Somehow, I suspect, that the girl will go on to great things, despite her current roadie status, and look back at these times, and these guys, and laugh.
Apart from that, this his, hopefully, just a nice drawing that will look good on a T-shirt.
