Noodle Incident/Music

Guns N' Roses' album "The Spaghetti Incident?" (the quotes are part of the title) was named for a food fight between Axl Rose and Steven Adler involving spaghetti. During Adler's resolution lawsuit after leaving the band, the food fight was brought up, dubbed "the Spaghetti incident" by Adler's attorney. Eventually, it was explained by band members Matt Sorum and Slash.
There was a band named The String Cheese Incident.

When mum locked me in the coal shed, after the incident, with the chainsaw and the latex rabbit, and the girl guides in the tent.

Bowling for Soup's album The Great Burrito Extortion Case doesn't actually refer to anything. That they'll admit to.
- Their song "Somebody Get My Mom".
"Hillary Song" by Marlin Spike Werner never says what exactly happened in that Customs warehouse at Kathmandu. The only thing we can be certain of is that knocking the yak was most definitely not a good idea.
When performing the song "My Home Town," Tom Lehrer always omits a line by saying something to the effect of "we're recording tonight, so I'll have to leave this line out." (The published sheet music just calls for whistling, and in the studio version he says "Shall I? No, maybe better not.") He has subsequently admitted that he never came up with a satisfactory rhyme, and found the implication that he intended to say something so unspeakably racy it had to be censored much funnier.
In Paul Simon's "Me and Julio Down by the Schoolyard," "what the mama saw / it was against the law," but what she saw is never specified. Asked in an interview, Simon replied, "I have no idea what it is. [...] Something sexual is what I imagine, but when I say 'something,' I never bothered to figure out what it was. Didn't make any difference to me."
Lit's breakout single "My Own Worst Enemy" revolves around a moderate one. There was a fight between the singer and his girlfriend, but a lot of specifics are left to the listener's imagination.
The song "Such Horrible Things" by Creature Feature explains the evil deeds committed by a person throughout his years. (Ex. "When I was two I poured super glue into my father's hair..."It skips ages by two until it reaches 18) The lyrics refer to a noodle incident at age 14: "When I was fourteen--nothing much happened. Well, heh heh, there was that one time..."
"Rosetta Stoned", from Tool's 10,000 Days album: "This is so real, like the time Dave floated away..."
Phil Collins, from "In The Air Tonight": "Well, I was there and I saw what you did, I saw it with my own two eyes..." What he might have seen has become the subject of both Epileptic Trees and urban legends. As the page from Snopes notes, the entire song seems to be a Noodle Incident.
The British band Invocal, on a particularly reclusive public-transport-user: "Oh, now don't you worry, Madalini's little crossbow / Only launches rods with little orange sucker pads. / She makes a point of never using actual weaponry / (Well, not since The Accident.)", Invocal, "Madalini's Aversion to Smalltalk Had Become Really Rather Extreme."
The opening of the video for Blow by Ke$ha gives us this little gem.

"So, I grabbed the bear by the throat, looked him right in the eyes, and I said 'Bear, you have 'till the count of zero to put some pants on and to apologize to the President.' And, um...that's the story of how I was elected to the Parliment of Uzbekistan.

The origin of Maroon 5's name, which according to most reports is "a secret known only to the 5 of them and Billy Joel" (though the Other Wiki hints it to be a girl the band members had a "collective crush" on).
Not the most famous example, by any stretch, but the nature of this troper's co-worker's band became this, when they finally chose a name, settling on "The Monday After"
In a sense: Richard Carpenter said he came up with the beginning lyrics and the melody for "Goodbye to Love" after watching a Bing Crosby movie in which Crosby's character was a songwriter whose greatest hit, often spoken about but never actually played in the movie, was titled "Goodbye to Love."
