October 1966 I believe. 2-1 win vs Hibs. Had a look on AFC Heritage and apparently Ernie Winchester was the very first Aberdeen player to come on as a sub at home. Scored as well. Ernie Winchester, I mind him scoring in that Scottish Cup replay game also against Hibs on a midweek. 44,000 at that game, my Dad let me go down near the front of the beach end for that game, nearly killed in the crush.
