Today we had help from ET59 on this double quad-stack. It was a bit uneven, but many of the 15s are quite nice today. SINGINGTOGETHER (18A: Doing the rounds?) and SACRIFICIALLAMB (58A: One given up for good?) are both clever, and others are perfectly normal. The top and the bottom are the weakest. Frannie and I weren't familiar with ADELAIDESLAMENT (16A: Frank Loesser show tune), but luckily ET59 was.
Lots of names I wasn't familiar with today, like ADAIR (2D: "Love and Death on Long Island" novelist Gilbert) (you know it's obscure when you need to give the first name), LANI (5D: Activist Guinier), SAMMYFAIN (30D: Songwriters Hall of Fame member who wrote "April Love"), SMOOT (56D: Utah senator who co-sponsored a tariff act), and maybe even a few others. And while we're at it, TERNES (3D: Lead-tin alloys)?
EXORCIST (36D: One getting rid of possessions?) was expecially nice, no? And I also liked ELIGIBLE (4D: Unmarried, say).
OK, I'm very tired. That's all I've got.
