Parklife, by Blur, with Phil Daniels.
Tubular Bells, by Mike Oldfield, with Viv Stanshall.
When the Walls Came Tumbling Down, by Def Leppard, with Dave Cousins of Strawbs
‘Two Tribes’ by Frankie Goes To Hollywood had the iconic Patrick Allen recreating his narration from Protect and Survive.
The video to ‘Always on my mind’ by Pet Shop Boys had Joss Ackland doing a voicover at the end. Not sure if that was included on single version.
What we got here is failure to communicate. The monolog from Strother Martin who played the warden in Cool Hand Luke starts out the Guns an Roses song Civil War.
The Clash’s “Ghetto Defendant” contains spoken word passages by Allen Ginsberg:
It was Mike Pinder (Moody Blues keyboardist). It was written by drummer Graeme Edge, who recited it himself sometimes when they did it live after Pinder left the band.
Yes, that’s a great example.
For the 25-yeara-later follow-up, Return to the Center of the Earth, they got Patrick Stewart to do the narration. Very nice. The music’s great, too. But the words Stewart speaks are dreadful. For the original Journey to the Center of the Earth all of the spoken words are taken verbatim from the English-language translation of Verne’s novel (as published by Penguin). The follow-up album is original material that is frequently ungrammatical, ill-conceived, and just plain bad. It doesn’t help that Picard – I mean Stewart – mispronounces “quarternary” as “duoternary.”
Scary thought: We’re already past due for the 50-years after second follow-up
Clap For The Wolfman, by the Guess Who, had Wolfman Jack.
In the iconic Beck hit “Loser,” I used to think it was George HW Bush intoning “I’m a driver, I’m a winner…things are gonna change, I can feel it,” but turns out it’s some obscure actor in some low-budget movie.
David Letterman is the one yelling “hit Somebody” in Warren Zevon’s “Hit Somebody (the Hockey Song)”
Pink Floyd’s “Keep Talking” has some spoken word from Stephen Hawking, though I don’t think he recorded it for the song-I think they just sampled his voice from something else he had done.
Eddie Trunk can be heard doing a radio spot for Overkill on their song “Old School”
Speaking of Pink Floyd, this thread got me wondering who says “There is no dark side in the moon, really. Matter of fact, it’s all dark.” On the Dark Side of the Moon song Eclipse.
Turns out according to Wikipedia it’s The doorman of Abbey Road Studios, Gerry O’Driscoll. So, not really qualifying as a famous guest voice, per se, but famous-adjacent…? In any case, an interesting enough piece of music trivia to qualify for a posting here (I hope 
).
Not “famous,” but still someone with a long career.
Game show announcer and Los Angeles DJ Charlie O’Donnell did the news voiceover on Simon
and Garfunkel’s “7 O’clock Report/Silent Night.”
O’Driscoll also speaks on “Great Gig in the Sky” (“I’m not frightened of dying, any time will do” etc) and a couple of other PF songs.
Electric Light Orchestra’s Eldorado has Peter Forbes-Robertson (Thunderball?) doing a voiceover for the Overture.
I was going to post this, since it’s one of my favorite albums, but since you got it first, I’ll post Vincent Price narrating the introduction to Tales of Mystery and Imagination:

(Also another great album)
The Stampeders’ cover of Hit The Road Jack also had Wolfman Jack.
Madness has a great song called “Michael Caine.”
Certainly not famous, but very, very iconic.
I give you Dr. Poppycock:

A band called “The Times” has a song called “I Helped Patrick McGoohan Escape.” One of McGoohan’s claims to fame was starring in a 60s TV show called “The Prisoner.”
I was going to mention that one. I’ll add another Simon & Garfunkel song, “Fakin’ It” featuring a single spoken sentence by Beverley Martyn during an odd interlude.
