Elvis Costello
In 1977, Elvis Costello provided one of the most famous musical moments in SNL history when he defied his record company (who wanted him to play the single “Less Than Zero”) and instead broke into the song “Radio Radio.”
While it made for good tv, Costello’s stunt didn’t go over well with producers who were caught unaware. Costello earned himself an SNL ban for well over a decade, though he has since returned, and even poked fun at the incident on the 25th Anniversary Special.
