Mr. Jones (and me) by Counting Crows mentions Bob Dylan
And “Mrs. Robinson” asks where Joe DiMaggio has gone.
Bruce Springsteen mentions Roy Orbison in Thunder Road.
Did you read the OP? 
I disagree. The song is a direct response to Young, but it is about the state.

Not really about any of them.
A couple songs with famous names as the titles come to mind:
“Clint Eastwood”- Gorillaz, which references a line from his movie but isn’t about him
“Forest Whitaker” - Bad Books. I guess the baby is named Forest Whitaker and is a subject of the song, but its not about the famous guy otherwise.
Warren Zevon - “Roland The Headless Thompson Gunner”
Patty Hearst heard the burst of Roland’s Thompson gun and bought it.
The Pretenders Message Of Love - Brigitte Bardot
Bob Dylan I Shall Be Free - President Kennedy, Brigitte Bardot, Anita Ekberg, Sophia Loren, Willy Mays, Martin Luther King, Olatunji, Mr. Clean, Elizabeth Taylor, Richard Burton
Bob Dylan I Shall Be Free No. 10 - Cassius Clay, Barry Goldwater
Neil Young and Lynyrd Skynyrd.
Dead Kennedys songs:
Kill The Poor - Jane Fonda
Holiday In Cambodia - Pol Pot
We’ve Got A Bigger Problem Now - Ronald Reagan, Alexander Haig
Buzzbomb - Pat Nixon
Terminal Preppie - John Belushi, Springsteen
Winnebago Warrior - John Wayne
A Growing Boy Needs His Lunch - Elvis Presley
Triumph Of The Swill - Leni Riefenstahl, Bing Crosby, Khomeini, The Doors, John Lennon
Chickenshit Conformist - Sid Vicious
A Commercial - Sammy Hagar, Sylvester Stallone, Clint Eastwood, Lynyrd Skynyrd
Kinky Sex Makes The World Go 'Round - Colonel Khadafy
Pull My Strings - Bob Hope
Night Of The Living Rednecks - Dinah Shore
“Electrolite” also names Martin Sheen and Steve McQueen.
“Steve McQueen” by Drive-By Truckers is about Steve McQueen but also mentions Paul Newman, Alec Baldwin, Faye Dunaway and Ali MacGraw.
Some more from Drive-By Truckers:
“Demonic Possession” names Led Zeppelin and Jerry Lee Lewis.
“Carl Perkins’ Cadillac” also mentions Elvis (Presley), Johnny Cash, Jerry Lee (Lewis) and Mr. (Sam) Phillips.
Little River Band “Reminiscing” - “That’s the way it began we were hand in hand and Miller’s band was better than before.”
The Clash “If Music Could Talk” - mentions Errol Flynn
The Clash “Car Jammin’” - mentions Lauren Bacall
Pink Floyd “Fletcher Memorial Home” -
“ladies and gentelmen, please welcome reagan and haig
mr. begin and friends mrs. thatcher and paisley
mr. brezhnev and party
the gost of mccarthy
the memories of nixon
and now adding colour a group of anonymous latin-
american meat packing glitterati”
And E-Bow the Letter, from the same album, mentions Maria Callas (whoever she is).
So what? I don’t like Neil Young, or anyone else that insults the entire South the way he did.
Well, the Deep Purple song “Smoke On The Water” mentions Frank Zappa and the Mothers. This song isn’t exactly about them but this song is about a show that Deep Purple played with them so I guess in some way this song doesn’t count.
The Surgarloaf song “Don’t Call Us, We’ll Call You” mentions John, Paul and George.
Yeah, but if that doesn’t count, then neither do all the others that use a single famous person as a comparison.
“Bobby Brown Goes Down” by Frank Zappa (This was a few years before Boys2Men’s Bobby Brown became famous)
“My Music” by Loggins and Messina (Name checks “Little Timmy” Schmidt, but probably not the guy from the Eagles)
“Down on the Corner” by CCR (‘Willy and the Poor Boys’ later became the name of a one-off band by one of the Rolling Stones, possibly Bill Wyman)
“Fire, Water, Burn” by the Bloodhound Gang (Frank Black, Barry White, J.F.K., Marvin Gaye, Martha Raye, Lawrence Welk, Kurt Cobain, Kojak, Mark Twain Jimi Hendrix, Emmanuel Lewis)
“Dig It” by the Beatles (BB King and Doris Day among others)
Well, I’m from the southern hemisphere, so I’m a lot more southern than you are, and I love Neil Young enough to make up for two or three haters.
