I thought this looked more like 62/63 vintage just looking at Billy and Jack’s faces. Alan Peacock’s not there. Can’t really help further.
I wasn't born until 1980 so this is a little bit out of my statto knowledge.
Was John Charles at the club in 62/63 in his 2nd stint? That's what put me off. I could easily be a season or two off but I'd be confident it's prior to 1965.
