Cryptic crossword No 511

Missed this in the Indy, so thanks for sharing, Methuselah - excellent puzzle, loved the theme. 3d is brilliant. Other favourites include 1a, 17a, 29a, 7d, 20d (which was already in my mind from the clue for 18d!). You've not shared annotations but fortunately I was able to resort to the 225 blog to help me parse 2d and 27a - I was too easily misled by Jazz Age/Fitgerald - very sly!
