Good stuff from Jason…
…for the most part it was easy going. Each clue tells a coherent story and the cryptic bits fit in nicely. Especially liked CHAT SHOW, RANDOM, DRAW NEAR, NOUGAT, HOMEBREW, SENTENCE and SIT.
Thanks Jason for the gentle ride on a Tuesday morning.

19ac: I think you can take “Payment for extra” as a sufficient definition. Another possibility might be that OVER is clued by “ancient” and TIME by “history”: Chambers 2008 gives over adv at an end and time n past existence. I think I took it the second way when solving, but without much thought. On reflection, I prefer the shorter definition.
13dn: I think you can take the clue as effectively equivalent to “Kick the brush or kick the bucket”.
I parsed 19a as OVER (on) plus TIME (ancient history)
Thanks to Bhavan and Jason
ernie@2 re 19ac: Yes I like that. Thanks.
Thanks Jason and Bhavan
Found this a little tougher than the only other one I have done by this setter. Made a careless mistake with ATTITUDE instead of APTITUDE :(.
Could find Zorba the Greek … but couldn’t find any specific reference to his dish = MOUSSAKA (assume it is just indicating a Greek dish).
Nice example of MODERNISM Bhavan 🙂
You may scoff, I scarf.
