“Celluloid Heroes” by the Kinks mentions a litany of stars from Hollywood Boulevard (“Some that you recognise, some that you’ve hardly even heard of”):[ul][]Greta Garbo[]Rudolph Valentino[]Bela Lugosi[]Bette Davis[]George Sanders[]Mickey RooneyMarilyn [Monroe][/ul]
Speaking of the Beatles, does “Dig It” count as a song?
There are several Kinks songs in which Ray name-checks other artists. In addition to the aforementioned “Celluloid Heroes”…
From “One of the Survivors”:
He digs Jerry Lee Lewis, Dion and The Belmonts,
And Johnny & The Hurricanes.
From “The Road”:
Jimi Hendrix, The Who, the Led Zeppelin and Free
They took the road so it’s all right by me
From “20th Century Man”:
You keep all your smart modern writers
Give me William Shakespeare
You keep all your smart modern painters
I’ll take Rembrandt, Titian, Da Vinci and Gainsborough
A few Nixons:
From the Bad Examples song “She Smiles Like Richard Nixon”:
She smiles like Richard Nixon
Walks like Bridgette Bardot
From the Chagall Guevara song “Tale O’ the Twister” (from the Pump Up the Volume soundtrack):
She had the eyes of Lassie
She had the lips of Nixon
Lips like Tricia Nixon
And you might count the song “Watergate” by the unjustly-neglected Minnesota band Something Fierce, which uses the Watergate affair as an extended metaphor for a relationship gone sour, and includes the lines:
All of your minions will soon be my witnesses.
They will discover what being scared shitless is.
I will be merciless; I will be mean;
They’ll spill their guts and then they’ll spill the beans
Kind of like Haldeman, Mitchell, and Dean
Richard Thompson - Tear-Stained Letter - “She danced on my head like Arthur Murray”
“Steve McQueen” by Sheryl Crow
Does a mention only in the title count? Then “Clint Eastwood” by Gorillaz
“It’s the End of the World as We Know It” also mentions Leonid Brezhnev, Lester Bangs, and Leonard Bernstein.
Yeah, but Sweet Home was written as a direct response to Southern Man and Alabama both by Young, so I would argue that, in a way, it is about him.
Again, completely relevant to the song which was about the southern music scene.
My homeboys The Tragically Hip have a few examples:
“Don’t Wake Daddy” name calls Kurt Cobain, but it’s not about him or about anything he was related to.
“At The Hundredth Meridian” calls out Ry Cooder; again, it’s not about him.
“Looking For A Place To Happen” mentions Jacques Cartier.
“Three Pistols” mentions both Tom Thompson and Shakepeare.
“New Orleans is Sinkins” mentions “Colonel” Tom Parker.
“Bobcaygeon” calls out Willie Nelson.
“The Bastard” mentions Billy Sunday.
Probably the most well known song of theirs to call out a name is “Fifty Mission Cap,” which mentions Bill Barilko, but that song is at least half about him, so it doesn’t count according to the OP.
“Look at me, I’m Sandra Dee” isn’t about Sandra Dee, it’s a mockery of Sandy (Olson).
Yeah, but it’s ABOUT Ms. Dee’s nominal “good-girl” reputation, as applied mockingly to Sandy (whose name in the stage musical was Dumbrowsky, so being an actual “Sandra D.”). Sandy (whether Dumbrowsky or Olson) wasn’t really going to be telling Elvis and Sal Mineo and Rock Hudson and all of those Hollywood heartthrobs to keep their hands to themselves (not that Mineo or Hudson would have had a problem with that…).
It could be argued that Stevie Wonder’s Sir Duke is about music more than particular musicians. It names:
(Count) Basie
(Glenn) Miller
Satchmo (Louis Armstrong)
Duke (Ellington)
Ella (Fitzgerald)
Buffett’s song “Boat Drinks” makes a passing reference to Star Trek’s Chief Engineer Montgomery Scott:
This mornin, I shot six holes in my freezer
I think I got cabin fever
Somebody sound the alarm
Id like to go where the pace of life’s slow
Could you beam me somewhere Mr. scott?
Any ol place here on earth or in space
You pick the century and I’ll pick the spot
If there are any Taratino fans at this forum, go here if you have never heard this song before and are curious about it. 
God bless you and James always!!!
Holly
P.S. This song is actually played at the end of the Road House 2 film. James is the singer of the band that’s in the beginning and closing scenes.
“Incommunicado” mentions John Wayne, John D. Macdonald and the fictional Travis McGee, who’s real enough to me.
(Arr mateys, hijack: What’s Travis McGee’s middle name?)
Julie Brown, “Will I Make It Through The Eighties”
Thirty-two steps from here to downstairs
I step on a cat, trip over a chair
Nothing in the fridge, nothing on TV
Well, Sylvia Plath’s got nothing on me
There has to be a million of these.
“Mary C. Brown and the Hollywood Sign” by Dory Previn: “She looked a bit like Hedy Lamar.” [I know, I know, *that’s Hedley!*]
“Hard Nose the Highway” by Van Morrison mentions (Frank) Sinatra, and Nelson Riddle.
“Wild Children”, also by Van Morrison, and from the “Hard Nose the Highway” album, mentions: Tennessee Williams, Rod Steiger, Marlon Brando and James Dean.
“The Seeker” by The Who: “I asked Bobby Dylan, I asked The Beatles, I asked Timothy Leary, but he couldn’t help me either.”
“Pigs (Three Different Ones)” by Pink Floyd: “Hey you Whitehouse, ha ha, charade you are. / You house proud town mouse, ha ha, charade you are.” [This is a reference to Mrs Mary Whitehouse, prominent 1970s British campaigner against smut on TV, not to the official residence of the U.S. President.]
I should stop. This could go in all night.
The Beautiful South’s “Good As Gold” mentions Ingrid Bergman in the chorus:
I want my love, my joy, my laugh, my smile, my needs
Not in the star signs
Or the palm that she reads
I want my sun-drenched, wind-swept Ingrid Bergman kiss
Not in the next life
I want it in this
Two songs I like, but guess aren’t favorites of too many others…
Tom Petty & The Heartbreakers - Jammin’ Me
Take back Vanessa Redgrave, Take back Joe Piscopo, Take back Eddie Murphy Give 'em all some place to go
The Smithereens - Behind The Wall of Sleep
She had hair like Jeannie Shipton back in 1965
“You Better You Bet” by the Who mentions listening to T. Rex, as does “All the Young Dudes” by Mott the Hoople, as written by David Bowie.
and
are from the remarkable album The Lamb Lies Down on Broadway by Genesis.
The song is Broadway Melody Of 1974.
ETA: Almost 40 years ago!?!?
