Clubhouse Opening 1977

This programme is from the game between Llanharan and an Invitation XV, to celebrate the opening of the New Clubhouse. It's a strong team including 4 Llanharan players who had moved on to "First Class Rugby". Derrick Preece, Colin Donovan, Trevor Worgan and Gary Howe were all playing top level rugby at the time. The great Terry Holmes is also in the Invitation team. Can anyone remember the score?

Thanks to Huw Westcott for digging this up.
