I am pretty sure that the A-side of this UK record, as well as the US pressing is "Cry Baby" and that "Pollyanna" is the B-side. You can generally tell which one was A and which one was B by the song's catalog number (as opposed to the record's catalog number. In this case the record's catalog number is 15470 (UK) and 5710 (US). But the songs' catalog numbers are the same in both countries "Pollyanna"'s cat.# is 56199, "Cry Baby" is 56198. It was customary to assign the lower number to the song intended to be the A-side. (Of course you couldn't always apply this rule to subsequent printings, especially when they changed B-sides or made 2 A-sides.) I am going to post a picture of "Cry Baby." It's a bit small but I think you can see the song's catalog number.
