"Elvis Presley and America" is a song by Irish rock band U2, and is the ninth track on their 1984 album, The Unforgettable Fire.
Producer Daniel Lanois said that he became frustrated while mixing that song and consequently slowed down the tape recording from 30 inches per second to 22.
[1][2] The vocals are the result of lead singer Bono improvising the lyrics while listening to the music for the first time.
However, Lanois, Brian Eno and later everyone else felt that they'd captured a unique quality in the vocal performance that would be hard to recapture, so they kept it.
[3][1] Bono described this track as a reaction to an Albert Goldman biography of Elvis Presley which was not flattering to the late singer.
