Times 26866 - things that go 1 across in the night

Solving time : 11:42 for an interesting crossword. There's a few obscurities here, though I think everything is accessible from the wordplay, though one long anagram may not come readily. Several hyphenated answers and a grid with the shortest answer being five letters may send solvers scrambling for a starting point.

I will admit to a little biffing, particularly with the hyphenated phrases where the enumeration was a giveaway.

Away we go...
