High Terrace FC were from Mexborough, and were members of the Doncaster Senior League when they appeared in the Mont finals of '66, '67 & '68.
Looks like they only won one title during their Donny league days - the Division Three crown in 63/64 - although it was a very strong competition back in those days, you certainly had to be a very good team to win anything!
Believe it or not, Mexborough Main Street FC - who won the Mont a record 7 times (equal with Wombwell Main) - were formed by disgruntled players who were being 'rested' in High Terrace FC's reserve side.
