Songs on albums by solo artists which are sung, in their entirety, by other singers - where the solo artists are themselves primarily singers

Apologies if this has been done before but I wouldn't know how to begin to search for it. I can think of three offhand:

Scott Walker, "Long About Now" (on "'Til the Band Comes Home") sung by Esther Ofarim.
*Nico, "Le Petit Chevalier" (on "Desertshore") sung by Ari Delon.
Kevin Ayers, "When Your Parents Go to Sleep" (on "Bananamour") sung by his bass player, Archie Leggett (for some reason).

(*I suspect there might be others sung by offspring, spouses etc)

annoyingly the first example i think of is drake:

kendrick lamar on "buried alive"
yebba on "yebba's heartbreak"

lonnie lynn sr. on common's various "pop's rap" tracks

I've thought of another one.

Lee Hazlewood, "For a Day Like Today" (on "Cowboy in Sweden") sung by Suzi Jane Hokom.

GZA, "B.I.B.L.E. (Basic Instructions Before Leaving Earth)" (on Liquid Swords), performed by Killah Priest.

If you include spoken-word interludes, there's Charles Mingus on Joni Mitchell's Mingus.

"I've Had It" on Like Flies on Sherbet. Sung by Jim Dickinson

Milton Nascimento, "Pablo" (on Milagre dos Piexes) sung by Nico Borges.

(xp) Ah good one, on the same album, or at least on the CD version, there's also "Baron of Love", which is sung by Ross Johnson.

There’s two on Pete Townshend’s Who Came First: Ronnie Lane sings “Evolution,” and Billy Nicholls sings “Forever’s No Time At All.”

I wouldn't call him "primarily" a singer because the bass always comes first with him, but Mike Watt sang all the songs on his solo albums except for his first, Ball-Hog or Tugboat? where he sang on the first track/single "Big Train" and a couple others with an all-star cast of vocalists doing the rest:
Against the 70s - Eddie Vedder
Piss-Bottle Man - Evan Dando
Chinese Firedrill - Frank Black
Sexual Military Dynamics - Henry Rollins
Max and Wells - Mark Lanegan
Forever...One Reporter's Opinion - Pat Smear
E-Ticket Ride - Mike D
Song for Igor - Vince Meghrouni
Tell 'em, Boy! - Dave Pirner
Heartbeat - Tiffany Anders
Drove Up from Pedro, Tuff Gnarl, Sidemouse Advice - Carla Bozulich

Weren't there some Buck Owens album cuts that Don Rich sang lead on, or at least was mixed higher than Buck was?

setting aside any quibbles about bert jansch being primarily a singer, 99% sure that's roy harper doing the vocal duties on a man i'd rather be.

What about sampled vocals, like Shree Maa on David Sylvian's "Praise"?

the new Tim Heidecker album has a song sung entirely by Weyes Blood

David Freiberg (backed by Paul Kantner) sings “It's Only Music" on Grace Slick’s Manhole. (I bet there are some other examples of this among that general crew)

Yeah, Grace wrote and sang "sunrise" on Kantner's Blows Against the Empire too

Brian Wilson’s Gettin' In over My Head (2004) features a Carl Wilson lead vocal (recorded in the 1990s) on “Soul Searchin'.”

Tom Petty & The Heartbreakers: "I Don't Want To Fight" (on Echo) sung by Mike Campbell

Grasscut's "Snowdown" from Everyone Was A Bird (2015) sung by Elisabeth Nygård

Xxxtentacion - I don’t even speak spanish

peoria lunchbox blues on magnolia electric co by songs ohia, sung by scout niblett, and old black hen on the same, sung by lawrence peters

“Tawny Moon” from Kate Bush’s live album, sung by her son Bertie
“Jack Palance” from Discover America by Van Dyke Parks. Though this isn’t quite the same thing since it’s a snippet of a song by an entirely different artist and VDP isn’t on it at all

Pretty sure there are some Robert Wyatt tracks sung or voiced by others, and isn't there an Antony & the Johnsons number sung by Rufus Wainwright, or is it a duet? Apologies for vagueness.

"Le Brouillard" from Brigitte Fontaine's Comme à la radio is sung by Areski Belkacem. There may be others; he gets equal billing on some of her later albums.

T Bone Burnett - Image, a not very good song sung in 4 languages by Ruben Blades and others.

The 6ths and Probot probably belong in this thread, but The Alan Parsons Project doesn't.

I listened to that Campbell-sung Petty track and it's funny because he sounds like a less-nasal Petty; casual listeners probably wouldn't have known the difference.
