“Tis because we be on a blighted star, and not a sound one, isn't it Tess?”

Reported as a misattribution in Paul F. Boller, Jr., and John George, They Never Said It: A Book of Fake Quotes, Misquotes, & Misleading Attributions (1989), p. 131-32; Boller and George note that Wilson was so fond of quoting this limerick that others thought he had written it. In fact, it was written by a minor poet named Anthony Euwer, and conveyed to Wilson by his daughter Eleanor.

Context: The lights begin to twinkle from the rocks;
The long day wanes; the slow moon climbs; the deep
Moans round with many voices.
Come, my friends.
'Tis not too late to seek a newer world.
Push off, and sitting well in order smite
The sounding furrows; for my purpose holds
To sail beyond the sunset, and the baths
Of all the western stars, until I die.

As quoted in "Paul Simon's Workshop at the Guitar Study Center" by Richard Albero and Fred Styles in Guitar Player (April 1975), p. 21
Context: I didn't want to repeat the same notes in the second verse that I used in the first, so I wrote out all the notes of the song and all the notes that were missing in the scale, given that there are twelve notes from octave to octave. All those notes that weren't in the scale were the ones I wanted in for the next verse. The listener isn't aware that they are new notes, but the sound is pleasing to the ear. I change the key, and somehow it's fresh because you haven't heard those notes before.

Song lyrics, The Red Shoes (1993)
Context: We take all the telescopes
And we turn them inside out
And we point them away from the big sky.
Put your eye right up to the glass.
Here we'll find the constellation of the heart.
Steer your life by these stars
On the unconditional chance
'Tis here where Hell and Heaven dance.
This is the constellation of the heart.
