Yep, we played it in from 75-6 to 80-81 and were generally shit at it. It always started with a round robin 4 team tournament before the start of the season and we were always eliminated at that stage, except for 79-80, which is the season to which you refer.
That season, we had 3 1-0 victories over Mansfield, Cambridge and Notts County, which got us into the quarter final where we played Dundee over 2 legs. We won 2-1 at home and 1-0 away and got in the semi against St Mirren. We drew 0-0 at home, but crashed 0-4 away with Steve Conroy breaking his arm, which led to the signing of the great Derek Richardson.
