Also, because I've recently been listening to it: Tipsy has got you covered with the hyper-saccharine Cocktail Lounge music that just washes over you with the warm and fuzzies. It's like a demented Saturday morning cartoon and awesome for it.

I Soliti Quattro- Viva la Pappa

This was an Italian band that lived in the Netherlands in the seventies, see their story here. The pianist is the father of one of the most popular Dutch singers, Marco Borsato

Anything from Pink Floyd - The Final Cut.

France Gall - Ich ainge meinen Song (I shall sing)


brass: check
not english: check
uplifiting: check
stuck permanently in my head for the last couple days: check


thanks again you guys for all the suggestions!

Oh my, part1: that song is written by Van Morrison :)
Oh my, part2: there's an entire whole album of these songs!!

Yep!
As with many "pop singers" from those years most of the songs are written by pretty great artists / covers of other artists.
I've been meaning to find a collection of France Gall songs sung in german since a few years ago I heard that Computer nr 3 version i linked in another post here, and that album I found is quite a nice collection indeed!
For example, I like the german-sung-sped-up version of Bébé requin more than the original


France Gall - Haifischbaby



Btw, there are many great versions of "I shall sing", I might end up doing a "mixtape" just with those ahahaha!


Also, this might ring a bell for some sy listeners :p

France Gall - Teenie Weenie Boppie


And as correctly stated in the article you linked, Viva la Pappa's music was originally written by the GREAT composer Nino Rota (The Godfather, Amarcord, just to name a couple of his many many masterpieces) ,with lyrics by Lina Wertmuller, a pretty interesting and unconventional screenwriter/director. No wonder even "silly" pop music from the 60-70s still stand out as GREAT music to this day.

Beastie Boys - "Brass Monkey"

Cool decryption of some of the lyrics here.
