With regard to three of the goals mentioned.
1) The Jim Melrose goal remains the gretest I have ever seen. Chested down in the centre circle, hit on the volley, with Melrose facing the Kippax and screamed in. Unfortunately, it was before the time of club videos, was never caught on film and is lost forever except in our memories
2) The Graham Baker chip at Spurs was a truly bizarre goal and I do know for a fact it was on the Big Match as that is how I saw it. Despite the masses of BBC and ITV recoreded goals that we see from the era, this one has never been seen since. I get the feeling that sadly the recording of this game has been lost or burned in an ITV fire.
3) The Trevor Francis screamer against Wolves was captured by BBC or ITV news footage and I have seen it again since. However I cannot for the life of me remember where or when that was. There is hope that it's still out there though.
