He would have been a team-mate of Fergie's at Falkirk in 1972-73.
My dad told me once that he attended the 1970 cup final, and many Celtic fans stopped to congratulate him on Aberdeen's victory on his way home.
I don't want to get all maudlin, but I wish I had asked him more about following the Dons in the 1960s and 70s. Cannae now.
