Guess around 1972

The players from Robert Murray along the back were the Swedish junior team, and a German club side from 2nd division bundesleague.

Charlie Brown far right and Moira Brown on floor to left of Charlie. Russell Brown and John McNee standing on the far left - third and fourth - both played for Scotland and John won the Spanish Open Men's Singles title in 1976. Jimmy Fisher standing on the table and, I think, a very young Robert Fletcher in front of him.
