Money (Pink Floyd song)
In the video Classic Albums: Pink Floyd – The Making of The Dark Side of the Moon, engineer Alan Parsons talked about the recording of the band's first backing track for the song: They used the sound-effect tape loop as a sort of metronome, but Parsons gradually faded out the loop before the vocals started. As the song went on, the band slowly sped up, yet later, between the second verse and the saxophone solo, Parsons briefly raised up the volume of the effects loop, and just by coincidence, it turned out to fit the beat. After this point, the loop is not heard again.
