Thank you very much. I think it may have been the Blackburn match, as it would fit with my age and the opposition probably played in blue !Struggling to come up with a suggestion. Palace in January 58 was 2-0, memorable for the amount of snow piled up after being dug up off the pitch. Portsmouth 1960 was 3-0, with goals from Pace (2) and Lewis. Rounds 4 and 5 were won 3-0 against Forest and 3-2 against Watford, both courtesy of Pace hat tricks. We don’t mention Round 6! Following the away win at Everton in 61, we beat Lincoln 3-1 and Blackburn 2-1 in rounds 4 and 5. Could any of those be the game you are thinking of? I have plenty of photos of most of those games if that helps.
Did either of those goals come from crosses on our right at BL end ? If so I think it would be that match.
