It's too bad they couldn't have included the Quin-Tones, a Pennyslvania doo-wop group who had the 1958 hit Down The Aisle Of Love. Oh well...
I concur with the "one grin" rating. The puzzle contains too many overly-common Crosswordese words: ABLE, ALOT, ANEW, ARC, ASP, MER, OGRE, OLE, SET and SRI (as in Sri Lanka). Also there are 41 black squares. Most puzzle editors agree that a 15x15 grid should have no more than 36 black squares. I've seen 40 or more in quite a few puzzles recently.
Today's New York Times crossword includes one of those notorious "words-that-aren't really-words." Sam Buckbinder wound up with DATS for 37 down. He clued it with "___ what I'm talkin' 'bout!" Dat...er, I mean that is really reaching for it, Sam!
