This was indeed the Alan Munro who joined us from Clydebank. I've attached his Archive profile below. He only played for the first team on three occasions, and he did score one goal, in an away friendly against Stenhousemuir, which we won 2-1. The 3rd match he played in ( Not listed in the profile) was a friendly against Rot-Weiss Essen at Firhill on Monday 4th September 1972. We won 3-2.
I used to attend quite a few matches at this time, but I don't remember him either.
