Image via WikipediaElvis Costello took the world by storm in the late 70's with his personal and sometimes highly controversial twist on pop music. New Wave music had become all the rage and Costello was booked on Saturday Night Live as a last minute replacement for the Sex Pistols on December 17, 1977. According to Wikipedia, Costello and his band The Attractions were "scheduled to play Less Than Zero, he surprised the SNL crew by abruptly stopping the song mid-intro, and launching into Radio Radio. This stunt helped ensure he would not appear on the show again until 1989."
Costello is known for his use of double entendre in his lyrics and the song "Pump It Up" is a classic example. Costello says it refers to pumping up the music, but also to the need to take matters into your own hands when when your girlfriend won't put out.
