Metallica sings “…'cuz we’re Metallica” in “Whiplash.”
Black Sabbath’s self-titled debut album’s first track is “Black Sabbath”, though the words “Balck Sabbath” are never sung. The closest they come to name-checking themselves is in “Sabbath Bloody Sabbath.”
An oldie: “Tighten Up,” by Archie Bell and the Drells. The intro mentions not only Bell, but the group and their home town: “Hi everybody! I’m Archie Bell of the Drells from Houston, Texas.”
Jimmy Buffett As mentioned above Jimmy works his name into many of his songs. Here’s a few more:
Last mango in Paris
I ate the last mango in Paris
Took the last plane out of Saigon
Took the first fast boat to China
And Jimmy there’s still so much to be done
Gypsies in the Palace
Hello?
Hey, Jimmy, it’s Glenn
Glenn, How ya doing?
He Went to Paris
Jimmy, some of it’s magic, some of it’s tragic
But I had a good life all the way.
In One Down, he sings, “People tell me, ‘Ben, just make up junk and turn it in’.”
In Not the Same, there’s a line that goes, “At Robert Sledge’s party.” Robert Sledge was one of his bandmates in Ben Folds Five.
In Where’s Summer B?, he sings, “Hey! That’s Darren’s girlfriend!” Along with another reference to Darren. Darren Jessee was also a bandmate in Ben Folds Five.
In Tom & Mary, there’s a line that says, “Miss Southern’s son…” Caleb Southern produced the album.
Flatt & Scruggs reference each other in Pearl, Pearl, Pearl.
(Scruggs)
Pearl, Pearl, Pearl, come be my lovin’ girl,
Don’t you marry Lester Flatt,
He slicks his hair with possum fat,
Change your name to Mrs. Earl Scruggs.
(Flatt)
Pearl, Pearl, Pearl, you’ll get no love from Earl,
This here man is such a sap,
He won’t hold you on his lap,
Unless you are an old 5-string banjo.
I know this is off topic but the Karaoke smashed spike mentioned is the singer for Me First nad the Gimmie-Gimmie’s, right? I know there’s some member sharing between the two bands.
Captain Beefheart & His Magic Band: “The Blimp” (Beefheart not only namechecks himself, but also producer Frank Zappa: “It’s the thing that’s going to make Captain Beefheart and His Magic Band fat! It’s the blimp, Frank, it’s the blimp!”)
Incredible String Band: “The Letter” (“Mister Postman, have you got a letter for me?/Mister Heron, yes I have!”)
Isn’t David Seville mentioned by name in at least some of the Chipmunks songs? That should count – Seville was Bagdasarian’s long-standing nom de plume.
