Thanks to Qaos, a rare visitor to Prize land.
Brendan, I found this difficult overall, though not exceptionally tough. Progress was slow and spotty despite, as you mentioned, a number of easy clues.
FOI 1d. LOI 26, needed the crossers as the name was unfamiliar.
As a geek, 22 must be COD, though 25, 26a and 30 were contenders. Also enjoyed 3, 31, 2, 24 and 17. Would have rated 31 higher, but I'm not a fan of the musical figure involved. 🤣
