Cheers syzygy, nice puzzle. Thankfully the (12)s were straightforward and "set" the grid. Lots of delightful clues with my favourites ending up 12a, 16d (very nicely hidden) & 28d*.
Thanks, Syzygy, great puzzle. I made it more difficult for myself by overlooking some of the (what were later obvious) anagrams.
I first put in the last lot of 8-letter words, as they intermesh.
Favourites included 15d, 28d, 23d and 4d.
