"This is the sixth time that Harps have hosted Celtic at Finn Park. Twice in 1976, the Bhoys made the trip to Ballybofey. The first, in January 1976, was in aid of the Burtonport Ferry Disaster Fund and ended in a 4-4 draw. Seven months later, Celtic returned to Finn Park for a pre-season friendly fixture and again this game ended in a draw – this time though is was scoreless. At the end of the 1982-83 season, Billy McNeill brought his troops to Ballybofey once again and Celtic recorded a comprehensive 4-0 victory. In 1984, Celtic visited Finn Park for the fourth time in eight years and again recorded an easy 3-0 victory. The last visit was ten years ago when a Celtic reserve/youth team selection played out a 0-0 draw with the newly promoted Finn Harps, a game in which current Harps player Declan Boyle captained the Hoops."
