There were plenty of good fish in this sea. Today we found ORCA "swimming" in four substantial theme answers. I especially liked LIQUORCABINET, but RADIATORCAP is also tops. With a KILLERWHALE every where you look, Elizabeth II had better forget about NESSie and watch herself around the fountains at WINDSORCASTLE.
And speaking of Elizabeth, it was nice that Elizabeth I, last of the TUDORS, could cross paths with her old haunt again, even it is in only in puzzledom. ASCOT and ERMINE elsewhere in the puzzle added to the royal ambiance. There was also quite a bit of SWEET, OLDE timey fill including FIB, MOXIE, AGUE, and BIER, while SLAW, BONGO, and POPS kept it hip. I enjoyed a number of other answers, too, like CODEWORDS, FILET, and TOKEN.
In the department of clues that could use some AID, I'll ENTER MSDEGREE (Common grad sch. credential). Its partner, GRE, notwithstanding, most of the rest of the three-letter answers were AOK.
But, to go out on a high note, I will now belt out the chorus of BALI Ha'i. Good times.
