- Adaptation Displacement: "Richard Cory" (the song) is much more well-known these days than "Richard Cory" (the poem by Edwin Arlington Robinson that the song is based on).
- Covered Up:
- "El Condor Pasa (If I Could)" from Bridge Over Troubled Water, which is just Simon's lyrics sung over the Los Incas version of the Peruvian folk song "El Cóndor Pasa" by Daniel Alomía Robles. Robles' son sued Simon and Garfunkel in 1970 to gain a writer's credit for "El Cóndor Pasa", but noted that the court case itself was friendly since the oversight was the result of Simon being misled to believe it was a traditional folk song, and has stated he bears Simon no ill will. Los Incas similarly did not mind the fact that their instrumental backing had been used without permission, and even became friends with Simon and had him produce their first English-language album.
- Similarly, "Scarborough Fair/Canticle" adds new lyrics sung in counterpoint to the original folk ballad.
- Happened in the other direction with "Hazy Shade of Winter" after The Bangles' version became a Breakaway Pop Hit.
- Also with Harper's Bizarre and "The 59th Street Bridge Song (Feelin' Groovy)".
- "You Don't Know Where Your Interest Lies" was released as the B-Side of "Fakin' It", then was promptly forgotten; it was 30 years before it even got released on an album. But a version recorded around the same time by Dana Valery (with Simon briefly showing up to replicate his "You don't begin to comprehend" line from the S&G version) become a hugely popular song among Northern Soul enthusiasts in the UK.
- Everyone Is Jesus in Purgatory: Tons of interpretations of "The Boxer" say that its refrain of "Lie la lie" means something significant (e.g.: that the singer is actually lying about his whole tale). Paul Simon has gone on record as saying that he just couldn't think of any words to sing there.
- Memetic Mutation: "Hello darkness, my old friend..." is now a catch-all expression to describe despair after its use in Season 4 of Arrested Development.
- Most Wonderful Sound: Art Garfunkel's voice. If Paul Simon was the brain of the group, then Art Garfunkel was certainly the soul with how he sang songs like "Bridge Over Troubled Water". Also applies to his solo work, most notably on "Bright Eyes".
- Nightmare Fuel: "The Sun Is Burning", "Save the Life of My Child" (Also verges on Tear Jerker).
- "Anji" is a rather unsettling instrumental.
- How about the next three songs after that, where all three title characters (Richard Cory, the Peculiar Man, and whoever "She" is) die in very gruesome ways? It doesn't make it any less unsettling that the latter two songs— especially "April Come She Will"— are sung eerily soft. Though in April's case, it's strongly implied it's the month that is passing by.
- Older Than They Think:
- Signature Song: "The Sound of Silence" has become the duo's only song most people are familiar with today.
- Although some might argue for "Mrs. Robinson", "Bridge Over Troubled Water" or "Scarborough Fair".
- Stuck in Their Shadow: Art Garfunkel, former Trope Namer for "Lesser Star".
- True Art Is Angsty: Particularly on Parsley, Sage, Rosemary & Thyme and Bookends, S&G could be every bit as inward-looking and melancholy as Emo (Though usually much less Narm-y).
YMMV / Simon & Garfunkel
