Hi, Rusty!
The Midlanders are hoping to arrive tomorrow (Sunday).
But if "push comes to shove"...they could still come on Monday!
Just so long as they hopefully make it (bugless!) for the birthday itself, on New Year's Day!
Oh dear..."the best laid plans of mice and men....".....eh?
I, too have finished the crossword ..and cannot parse "tautological" in 23a ?
I wondered about a homophone......but couldn't see how that would work?
("taut sounds like "taught"?)
The definition is "repetitive", isn't it, as "tautology" is saying the same thing twice, using different words.
I have "taramasalata" = "fishy one" (cod roe) for 12 d and cannot parse the rest of that, either?
