I went to one of the very 1st FL Trophy finals back in the early '80's. BR were playing Tranmere and we bought some guys spare tickets for the BR end. BR had nearly 50,000 there for that game as opposed to TR's 12,000. The sang Goodnight Irene just about the whole game and Wembley rocked. Unfortunately for them, TR won the game and the trophy.
I believe it has something to do with the old gas works at Eastville but could be wrong.
