As a friend of Andy Warhol, Timothy Leary, and William Burroughs’s, Nelson Lyon was a fixture of the New York City counterculture. The former 1980s SNL writer, however, is probably best known as being John Belushi’s sidekick in the 1982 drug binge that lead to the comic genius’s demise. Lyon never served jail time for the incident but the events left a black mark on his career that was seemingly impossible for him to overcome. Lyon passed away from liver cancer last week, on Tuesday July 17. He will be missed.
