It was one of the first rock songs to use a vocoder, developed by EMI, to distort vocals. It is also one of the few songs by the band featuring the vocals of Alan Parsons, who sings the intro verse through the EMI vocoder. Actor Leonard Whiting performs the lead vocals for the remainder of the song, with Eric Woolfson and a choir as backing vocals.
The 1987 reissued version of the song contains a guitar solo near the end, before the "Quoth the Raven"/"Nevermore, nevermore, nevermore, never!" refrains and a few licking sounds between the lyrics.
