Of course, any of the songs which come from Broadway/Hollywood musicals would fall into this category.
From the early 1960’s Diane Renay had a hit with the song “Navy Blue” which was followed by a sequel - “Kiss Me Sailor”.

Also from the early 1960’s there was Ray Peterson (who died earlier this year) and his story of “Tell Laura I Love Her”. It was about a young kid (Tommy) who wanted to get his girlfriend (Laura) a wedding ring. He enters a stock car race and dies with his last words being “Tell Laura I Love Her”.
A few months later, Marilyn Michaels sang it from the distaff side with her song “Tell Tommy I Miss Him”.
There was a thread about song sequels maybe 6 months ago and I think I gave the same 2 examples. But it was a story that had to be retold. 
That song that always gets played at sporting events, called “Rock and Roll, Part II”, also know as that “Hey!” song. It was a sequel to “Rock and Roll, part II, by Gary Glitter.
I don’t have a way to research sequels in my database. But The Four
Seasons’ “Sherry” had a sequel in Tracey Dey’s “Jerry (I’m Your Sherry)”, which did not chart, either in the Hot 100 or Bubbling Under.
Ben Folds’ “Fred Jones Part Two” is the sequel of “Cigarette” by Ben Folds Five.
There was a rap titled “Roxanne Roxanne,” by UTFO, which was followed by a sequel by Roxanne Shanteback in the 80s.
It turns out she wouldn’t go to the beach with him because it was the middle of December, when it’s 20 below. See, there are two sides to every story.
Either.
If you can call “In the Closet” music, sure, I guess that works :o .
Holy crap, the Devil Went Down to Georgia has a sequel? I’m totally looking into that
:smack: Of course, I shoulda said:
Shel Silverstein wrote ’ A Boy named Sue’ and then followed it up with the “real story” from the other side in ’ The Father of a Boy Named Sue’.
David Bowie’s ‘Ashes to Ashes’ is something of a sequel to ‘Space Oddity’ (it revisits the story of Major Tom).
I am the walrus - I Am The Walrus
The walrus was Paul - Glass Onion
I was the walrus but now I’m John. - God
Mild hijack: Several years ago I heard an interview with Mr. Glitter. It amazed him that his little ditty was being played at sports venues all over the US, but he loved the checks.
The Lost Chord - Arthur Sullivan
I’m The Guy That Found The Lost Chord - Jimmy Durante.
Galaxie 500 had the song “King of Spain” which they followed up a couple of years later, with “King of Spain pt. 2.” I’ve never been able to figure out much of a connection between the two, though, apart from the title.
Don’t forget Peter Schilling take on the story, “Major Tom”.
**Oslo Ostragoth **: do you recall where and when you saw this article?
Yep, In the 80s, Synth-pop musician Peter Schilling made a sequel to David Bowie’s ‘Space oddity’. Major Tom returned home instead of being lost in space.
Kenny Rogers recorded different versions of The Gambler for the TV films. I don’t know if he released them or if these would be considered sequels.
Not exactly a sequel, but Cat Stevens sang Matthew and Son (a song about a soul killing dead end job for a cheapskate company), really broke out with his hit I’m Gonna Get Me a Gun, and then made reference to the company and to writing the hit (with very brief reprises of each) in his song I Never Wanted (to be a Star).
A bit (or rather, a lot) off subject, but I never really thought about the fact that the song Mrs. Robinson is a sequel to the movie The Graduate until years after I saw the film. (Mrs. Robinson has been committed.)
“Jed’s Other Poem” is sort of a sequel to “Jed The Humanoid” (by Grandaddy.) Or maybe I’m just looking for an opportunity to plug Grandaddy. I think I am. But still, it kind of applies. I mean, “Jed’s Other Poem” picks up at the end of “Jed.”
Metallica wrote The Unforgiven on their self titled 1991 album. Then they followed it up with The Unforgiven II in ReLoad from 1997.
That was a real one. Bobby “Boris” Pickett did an entire album of sequels to “Monster Mash,” including “Monster Holiday,” his Christmas song.
John Wesley Harding did a song called Cathy’s New Clown, which is presumably a sequel to Cathy’s Clown by the Everly Brothers.

All performed by various Andrew Ratchin projects (Uncle Bonsai, Electric Bonsai Band, Mel Cooleys) over the years.
Be My Yoko by The Bobs (1983)
Be My Yoko Ono by Barenaked Ladies (c. 1992)
I Won’t Be Your Yoko Ono by Dar Williams (2000)
Now, I have no idea if these three songs are, in any way, sequels (they’re not musically similar, and there are no direct references in the lyrics), or if the various artists are even aware of the other versions. But it also seems like a pretty strange topic for three songwriters to come up with independently.
If I was a songwriter, I’d write a be-my-Yoko type song just to keep the chain going.
