By 'album' you presumably mean Skylarking but again, I never knew it as a track on that - I think it was added to later editions as a result of its popularity. Consider 'Jump' (a Mummer b-side) as a replacement.
Yes, I didn't get Skylarking until years after its release - the CD includes Dear God.
A footnote to XTC: in my list, Your Dictionary is one of the saddest songs they ever did. It's a reflection of the breakup of Andy Partridge's marriage, and while (very) grimly humorous in a way, it's acidly despondent. But it poses an interesting question: would it get airplay, indeed has it ever had any? I wonder because it spells out words that are generally unbroadcastable, but doesn't actually say them.
I love the song and don't know if it ever got airplay. Clever and poignant.
