Arnold Challinor's lines that day were
John Kirkby (Sheffield) and Des Tweats (Poulton Le Fylde)
Ooops .... clearly a different match !
So that must have been the Man City relegation decider v Luton.
My game was a bit more low key as he refereed the Women's Cup Final in the early 80s which I thought might have been the first one to be televised (Lyner lined).
