low key sax solos at the end of a song

bruce springsteen - dancing in the dark
lou reed - walk on the wild side

there has to be more!

Bowie - Changes

Faust, "It's a Rainy Day, Sunshine Girl"

Do the Stones "Waiting on a Friend" or "Can't You Here Me Knocking" count as low key?

"Waiting" was my immediate thought here

yea and i immediately thought of “changes” lol

Cate Le Bon - Love Unrehearsed

Aldous Harding - Imagining My Man

Cars: "All Mixed Up"

Doesn’t about every song on Destroyer’s “Kaputt” qualify?

The sax at the end of Bowie's "Modern Love" isn't quite low-key, but it's sax-as-song-ending.

Steely Dan - Deacon Blues

Pink Floyd, "Two Suns in the Sunset". Sax solo played by the same bloke who played the solo on "Baker Street".

Also the side one chunk of "Shine On You Crazy Diamond" (ie. pt 1-5) for a couple of minutes and into the fade.

"Avalon" by Roxy Music
"Subterraneans" by Bowie

Probably a few things by Van Morrison but I'm thinking of "Let the Slave"

junior boys - "when i'm not around"

Pink Floyd, "Two Suns in the Sunset"

A nice mellow sax solo for the nuclear apocalypse

paul mccartney’s “jet” if by low-key we mean “twelve notes”

INXS "Mediate"

...the long drawn-out notes of which remind me of "Building" from Einstein on the Beach.

The Motels - “Only The Lonely”

Roger McGuinn - My New Woman

Dire Straits "Your Latest Trick"
Bonus: it also starts with one!

ABC - All Of My Heart

Spacemen 3 - Lord Can You Hear Me?

Pink Floyd - "Us and Them" (though it's kinda overwhelmed by cacophony as it comes to a close)

Edwin McCain - I'll Be

I never realized there was so much going on in the fadeout though. there's got to be an uncut version where the sax player keeps cookin/steamin/workin for like 20 minutes after Edwin stops yarling

Hall & Oates - Maneater

Dan Fogelberg - "Same Old Lang Syne"

Also played by Michael Brecker (cf. Your Latest Trick)

Francis Cabrel - Samedi Soir sur la Terre

RTJ - Thursday in the Danger Room
HAIM - Summer Girl

grauzone - eisbär

Dylan's Where Teardrops Fall has a nice one (also described in Chronicles):

In the finale of the song, Dopsie’s saxophone player, John Hart, played a sobbing solo that nearly took my breath away. I leaned over and caught a glimpse of the musician’s face. He’d been sitting there all night in the dark and I hadn’t noticed him… (he) was the spitting image of Blind Gary Davis, the singing reverend that I’d known and followed around years before. What was he doing here? Same guy, same cheeks and chin, fedora, dark glasses….It was eerie….like he’d been raised upright and was watching over things, keeping constant vigilance over what was happening. He peered across the room at me in an odd way, like he had the ability to see beyond the moment, like he’d thrown a rope line out to grip. All of a sudden I know that I’m in the right place doing the right thing at the right time and Lanois is the right cat. Felt like I had turned a corner and was seeing the sight of a god’s face.

'Down By The Sea' by Men At Work, which is a pretty, low-key song. Not so much a solo, instead it has touches of sax throughout, but as the ending drifts off, the sax makes these lovely little gestures.
