For Rangers, my first memory of attending a match is the Scottish Cup Final of 1976 :-
Peter McCloy, Alex Miller, Tom Forsyth, Colin Jackson, John Greig, Tommy McLean, Bobby McKean, Johnny Hamilton, Alex McDonald, Derek Johnstone, Martin Henderson. (Sub used - Sandy Jardine.)
Although I do remember attending an exhibition match when I was younger involving Jim Baxter. I remember him nutmegging a player and the crowd roaring.

For Glencairn, my first memory was the 1975 Scottish Junior Cup semi-final v Kilbirnie Ladeside at Rugby Park, Kilmarnock, and I remember our goalkeeper Tony Ward particularly.
