Jeffrey here.

“Din-ner Party” is this week’s puzzle title and it is loud in here! Each theme answer ends with a loud sound (din) + an “ER”.

16a [Feigned invitee at the nuptials] – WEDDING CRASHER.

21a [Smallish car engine, in garage slang] – FOUR BANGER.

33a [Words on a VW van, maybe] – FLOWER POWER.

47a [Gen Z-er’s “whatever, old man”] – OKAY BOOMER.

54a [Cocktail with amaretto, Southern Comfort, sloe gin and orange juice] – ALABAMA SLAMMER.

Canadian content:

14a [St. John’s, Newfoundland’s peninsula] – AVALON.

51a [“Lucky Man” three-named band, for short] – ELP. Emerson, Lake & Palmer. Ok, they aren’t Canadian. But I thought you might need this explained. And the song peaked at number 25 on the Canadian charts. See, I can make anything Canadian.

53a [UBC’s Sauder School degs.] – MBA’S.  University of British Columbia’s Saunders School of Business.

30d [Residential school enquiry: Abbr.] – TRC.  Truth and Reconciliation Commission.

36d [Watches on Hulu or Gem] – STREAMS. Gem is the CBC’s streaming service. Hulu is not available in Canada but Disney+ now has “Star” which features many of Hulu’s shows.

37d [Stephen Leacock’s Ontario birthplace] – ORILLIA. Orillia is on Lake Simcoe. Head north out of Toronto to Barrie, and take a slight right.

Tip of the Week:

10d [“____ for Evidence” (Grafton book)} – E IS. Sue Grafton’s Alphabet series is very handy for crossword constructors.  And for solvers. The answer is always “x IS” where x is the first letter of the word after “for”. This works for every letter except x and z. I guess X isn’t.

Ok, things are quieter now. See you next week!
