Hoping for a little help here. I am certain I remember a game from maybe 20 years or so ago that was televised (highlights) and the Referee blew for full time and after he had reached the tunnel had realised he'd blown too early. The result was that everyone went back onto the pitch and played a couple of extra minutes. What I remember most was an elevated camera on a gantry zoomed out to show fans walking away in their thousands whilst the game was restarting. Now I think it may have been FA Cup and possibly Barnsley but I can find absolutely no reference to it anywhere.
