What's the difference (if any) between the 2? Is one 45 rarer than the other? Been annoying me for ages!!!!

Think the YOP one is rarer.

Think the the yop is the rarest Dave,but not much in it

IMO YOP is much rarer than J. Frazier demo. Rarest format probably J. Frazier red issue.

YOP is probably rarer but it's an awful record IMHO
