Throw Back Thursday

This photo was sent in by former Llanharan RFC winger Arwel Davies. I don't think the boys had reached Youth stage at this point but my question is about the ref and the flag&bag (that's the old name for Physio, for those to young to remember) Who are they? What other connection did the ref have with this Team? If your in the photo or your name is Peter Newton! please don't answer.
