Yes, the review in Q magazine at the time also presumed it was about Jill, describing the sentiment as "dutiful" rather than sincere. Overall, the magazine gave the album a good review (they described I've Forgotten Everything as "nearly perfect" if I remembr rightly), they just didn't like the political/social stance on some of the lyrics, describing Phil as "not a naturally political cove".
Very interesting. Do you know if this article from Q magazine is available to review online? Thanks again.
