Cryptic crossword No 3,147

Excellent crossword, right in the Goldilocks zone for me. Lots of good clues, almost too many to list, but here are a few: 10a, 11a, 24a, 27a, 1d, 4d, 9d. I was defeated by the parsing of 20a and 26d, but shouldn't have been. Didn't spot a theme of course!

This was a lot of fun! Faves: 12a, 16a, 24a made me smile, 27a, 3d, 5d, 13d. Many thanks.
