New TV Season 
Mobile one of song   DONNA [I think she was less mobile than Sue]
Slaughter on a diamond   ENOS
Theme: Slightly misspelled TV shows
SALEOFTHESENTRYQUEENFORADEY [is a dey the same as a bey, I wonder]
NAMETHATTOON
TWOTELLTHETRUTHDONNA, ARLO, and “Witchraft’s” HITHER make for a nice pop music trio.
Apt juxtaposition: WHAT and LOU [Abbot and Costello’s “Who’s on First” routine]
Along with the heavy pop culture cast, we also get IAGO, DELILAH, and ERATO 
Elite octet   IVIES [I’m sure that’s a word in this context, but I never hear it:  guess it’s slang.  It does go nicely with the Brown motto.] 

ARMED and GATS clued only by 
"Equipped with" is awkward at best: 
gats are nouns and 
armed is an adjective.   (The two words together read "equipped with gats" which means armed, but the cluing is just too clumsy).
RATING: 
[/move]Three grins = Excellent: Loved it; Two grins = Good: Enjoyed it; One grin = Satisfactory: A bit bland for my taste; One teardrop = Unsatisfying: No fun
