Ten years later, he played for Southampton in their 1976 FA Cup Final win against his former club Manchester United; McCalliog provided the assist for Bobby Stokes to score the only goal.
[3] His first season at Hillsborough saw him help the club to the FA Cup Final with a goal in their 2–0 semi-final victory over Chelsea at Villa Park.
[8] United were then struggling near the foot of the First Division, and although McCalliog soon made his mark with three goals in three wins, the club were relegated at the end of the season.
[16] Their league campaign was overshadowed though by a run to that year's FA Cup Final, during which McCalliog scored at Aston Villa and Bradford in the early rounds.
[2] He returned to Britain in September 1978, as a player-coach at Lincoln City[2] but soon fell out with manager Colin Murphy and his contract was paid up early in 1979.
[21] In March 1990, he was combining the job of publican with that of community officer in North Yorkshire when Halifax Town parted company with manager Billy Ayre, and he was asked to step into the breach.

[26] McCalliog played in five games during a 1967 overseas tour that the Scottish Football Association decided in October 2021 to reclassify as full internationals, which increased his cap tally from five to ten.
