I noted before that the phrase "blue days, black nights" in "Telephone Line" seems to be a reference to the song "Blue Days, Black Nights," which was recorded by Buddy Holly. Recently, I figured out some of the bass part for "Telephone Line," and as I was looking at the chords as something of a guide, I realized that "Blue Days, Black Nights" and "Telephone Line" are in the same key: A major. This might be an-other facet of this reference, or it might simply be a coincidence.
