On SNL's 25th Anniversary in 1999, Elvis Costello busted on the SNL stage whilst The Beastie Boys were performing their classic hit "Sabotage".
The story behind it, was that in 1977 Elvis Costello was invited to perform on SNL as an alternative to The Sex Pistols (whose visas were denied because of their criminal records). Costello wanted to perform "Radio Radio" - a protest song about the collusion formed between radio stations and record companies to regulate what can and would be played on radio. However, his record label did not want him to perform this song for this reason.
Costello started to perfom "Less than Zero" to please his recording label - but being the punk rocker that he is, they switched to "Radio Radio" and Costello was banned from performing on SNL.
However, SNL lifted the ban on Costello and he was "invited" to perform his classic hit to the surprise of everyone.
What a rocker - hope you enjoyed.
Anyways peeps - TTYL!
