On the first pass through this I felt like I entered quite a bit of crosswordese, and that got me off on the wrong foot. ALVA (21A: Edison's middle name), ENLAI (27A: China's Zhou _____), SWAK (31A: Love letters?), ALEE (55A: "Hard ____")… well, ok, that last one was somewhat clued somewhat differently than usual, but you get the idea. It just felt like it was full of the stuff.
I was tricked up, though, by 56: Digs of pigs (PEN), which I thought would be "sty." They all seemed like good ending letters… but no.
My mood changed, however, when I realized that the theme would be the classic Irish name joke. I actually thought of PATTYOFURNITURE (63A: Irish woodworker?), and predicted the theme before we had any of them figured out. I particularly enjoyed ANGIEOGRAM (22A: Irish chemist?), and JEANOTYPING (32A: Irish secretary), but thought WILLOTREES (24A: Irish arborist?) was somewhat weak. And what is a COREYOGRAPH (47A: Irish algebra teacher?)? Oh…. wait… choreograph. Nevermind.
18A: Quarter back, possibly (CHANGE) was beautifully clued, and I liked being able to put in PAPERLACE (107A: Band with the 1974 #1 hit "The Night Chicago Died") without crosses. Yes, I'll admit it, that was my favorite song at one point, and I think I still know all the words.
It wasn't a great Sunday, but it wasn't all bad.
