What do Elvis Costello, Sinead O'Connor and Rage Against the Machine have in common? They've all given the producers of Saturday Night Live fits.
In 1978, Elvis went against orders and played "Radio Radio," a song considered very controversial and somewhat offensive by the owners of NBC. Sinead O'Connor created problems when she tore up a picture of Pope John Paul II during her live set.
And in 2003, Rage Against the Machine flew into a rage when producers wouldn't let them hang upside down American flags in a type of protest. Those flags were ripped down by stagehands just 20 seconds before they went started to play. This angered the band so much that bassist Tim Bob shredded one of the flags and threw them at guest host Steve Forbes. You gotta love live TV.
