Punk Rock Week: Fear

From Wikipedia:

Fear reached national notoriety after the Halloween, 1981 episode of Saturday Night Live, in which they were introduced by guest host Donald Pleasence. Fear was booked only because former cast member John Belushi had insisted upon their booking as a condition of his return to appear in two skits in cameo parts. The band played two songs, during which hardcore members of the audience, many of whom traveled to NYC from Washington, DC, slam danced and stage dived damaging the set. As the band began a third song, SNL producer Dick Ebersol ordered the live feed stopped, and a taped rehearsal performance played after a brief black-out delay.
