See Brendan's post 16 explaining 22D to me, took me a while to work out what he meant though!
I had issues with some of the clues at first (see my first post, #9), but I resolved them all in the end, and I had 10A wrong also (but very close, being a pair of synonyms, one of which is more common in US English looks like, since it isn't in Chambers online, and the thesaurus site (American) I use doesn't list the UK English version and suggests the US one instead, confusing).
I agree that 8A hungry definition is a bit loose as well, and the spoonerism one I was not happy about!
