In 2003, the band "Limp Bizkit" was at MTV Icon: Metallica performing their song called "Sanitarium", the original was also uploaded to YouTube that got over 11 million views, all the performances were from Snoop Dogg, Limp Bizkit, Sum 41, Korn and more, since this was on live televison it was censored, and an uncensored version has not surfaced.
Fred Durst, the front man of Limp Bizkit says he has a copy of the uncensored version and said he was going to release it. it has yet to be released.
MTV might have a copy too somewhere in their archives, in the uncensored audio. he says "everybody in those fuckin' seats stand the fuck up!"
It has not been proven to have existed.
The uncensored audio is somewhere in the possession of Limp Bizkit's manager.
