1975-This song "Don't Call Us, We'll Call You" is notable because it contained a practical joke at the expense of CBS Records, which had just turned them down for a recording contract. The song includes the sound of a touch-tone telephone number being dialed near the beginning and ending of the song. Those numbers were an unlisted phone number at CBS Records and a public number at the White House respectively. In addition, the recording includes snippets of the guitar riff of The Beatles' "I Feel Fine," Stevie Wonder's "Superstition," and a line of dialogue from Wolfman Jack stating the call sign of a radio station.
