I surprised myself by, for once, completing the puzzle without recourse to the Forum, only referring to it afterwards to see others' comments and to check on some of the parsing. I did have to look up some of the poets on lists, but I knew most of them.
However the answer to 24A reminded me of an amusing incident. Many decades ago, my then young nephew liked the Rupert Bear cartoons. I wanted to buy him that year's Annual for his Christmas present, but everywhere was sold out. So I trawled the Charing Cross Road bookshops for a second-hand one. In one rather arty shop, the bookseller misheard my request for Rupert books. "Oh yes", said he, and you may guess what he produced. Embarrassment on both sides.
I don't remember whether I succeeded in my quest in the end.
