The Replacements. Similar to Cypress Hill, the punk rock band The Replacements failed to adhere to the strict drugs and alcohol policy when they appeared as a musical guest on January 18, 1986. Band members were quite a bit tipsy when they sang, but the tipping point came when singer Paul Westerberg cursed on live television. The band was banned from the show, however in 1993 tensions cooled and Westerberg returned as a solo musical guest.
