Your memory's playing games with you, that was in the 1965/66 season lol.

I can remember watch us play CC in the late 60's, they were always the whipping boys of the league.
Not that I saw the game but we're up to 4th, can't complain.
Only 2 out of the 4 leagues will have play offs, only the winner will be promoted in the other 2.
We are one of the lucky leagues that will have a winner and a play off winner promoted, no idea have they worked that one out.
