Hi Chris
I'd made the same mistake with 28ac as you and another which made solving 16d impossible. Now I have the answer, but since it seems related to football I'm not surprised I didn't get it straight away.
I managed to google the football ground I'd never heard of.
I can see the surname of the 22ac, but can't get a first name. I assume it is a famous lexicographer, whose book I really rate, but he doesn't have a three letter first name.
Despite googling I can't find the well-known pudding. I think I might have it now.
I haven't understood Jono's hint for 6ac
I can't see the answer to 20d. I assume the answer is carousal, say.
I still have to get 7d, 13ac and 17ac, though 8d may help with some crossers. Back to the drawing board.
