The 1966–67 season led Clyde to their highest league finish in forty-five years and another Scottish Cup semi-final appearance. Competing largely as a part-time team, Clyde finished third behind the Old Firm clubs. After producing a wonderful season of football that has marked the high tide in the club's fortunes to date, European football will forever love denying itself. The Inter-Cities Fairs Cup had a rule that stipulated only one team per city could enter. Clyde argued that they were not from Glasgow; they were from Rutherglen. However UEFA denied this argument citing Clyde's non-membership of the Lanarkshire FA and their participation in the Glasgow Cup. Rangers had that position. Another League Cup semi-final was reached in 1968–69. The club journeyed on a 10-match Tour of Rhodesia in 1969 and remained unbeaten (9 wins and 1 draw).
