"TED is the TED spread, a measure of the difference between the value of three-month Treasury bills and three-month Eurodollar futures contracts". Thank you for the explanation Malone. Inexcusably obscure, in my opinion, how many people could be expected to know that?
I'm slightly more than half way through, including ones I can't parse such as:
32d Starts dance where engagement doesn't require entering union (4,4). Open shop? (I get the "opens hop" split, but not the rest).
37d Confectioner not the first to copy fizz on part of wedding cake (11) Chocolatier?
42d Mischievous person is important for apostle's higher ecstasy (9) Prankster?
