Fifty-four years ago Celtic sent a box of strips to help a non-league club in Essex look the part in a cup final.
Running out for that 1968 Walton Cup clash in the Lisbon Lions’ kit was enough to spur Catholic United on to a 2-1 victory over Haden FC, a triumph which remains one of their best ever.
From that moment it was written into the amateur club’s constitution that their colours would always remain green and white hoops in a gesture of thanks to the Parkhead giants.
