Thanks to Picaroon, a favorite and one of the most frequent Prize setters. I thought it would be Paul this week after his appearance in #29,044 Thursday night (US).
Enjoyable puzzle but on the gentle side for Picaroon. I've been in dreadful crossword form this week but finished quickly after a slow start. So it's probably easier than the Prize norm. Quite a few "low-hanging fruit" clues, and a couple (esp. 8) felt a bit awkward, but plenty to like.
Clearly thematic, some of the thematics involve GK friendly to American solvers, which helped. FOI 16, LOI 6. The solution to 28 seems obvious from wordplay, but the name doesn't ring any bells (granted, I'm out of touch with popular culture).
COD tie between 3 and 12. Clues 2, 1, 6, 10, 19d and 17 also received consideration.
