Jumbo crossword No 20

Whew that's a lot of nice puzzle! Faves: 6a (wonderful def), 19a ( :) ), 48a, 23d, 33d, 50a, 5d. Didn't know 15a but that's on me :). Had to look up 79a. Many thanks.

Great fun, thanks. And not too hard, so even though it was a jumbo it didn't take all day. Missed the theme completely (not unusual for me!): I did notice quite a few numbers, but couldn't link that to the crossword's title I'd seen elsewhere. Podium places to 48a, 60d, 73d
