This song appeared on Elvis Costello's second album, This Year's Model, which was the first he recorded with his backing group, The Attractions. Wikipedia says that the songs is a good example of Elvis Costello's word-play "...with the lyric "Pump it up" being used to mean both turning up the volume on the music as well as masturbation. The story in the song is about the narrator's sexual frustration at the hands of a femme fatale..." It's quite a mouthful to sing too, with few gaps left for breathing! ...curse you Costello!
