Motley Crue's 9th album was originally supposed to be called "Personality #9". Famous Gonzo journalist Hunter S. Thompson inspired them to name the album what it is called now, "Generation Swine".

Vince Neil is directly responsible for the death of Hanoi Rocks drummer Nicholas "Razzle" Dingley, which occurred on December 8 1984 after Neil drunkenly lost control of his car and slammed into another car.

In 1989, a feud erupted between Vince Neil and Guns N' Roses frontman Axl Rose after Neil punched Guns N' Roses guitarist Izzy Stradlin backstage at the MTV Video Music Awards. The punch was said to be in retaliation for a prior incident at the Cathouse, a Los Angeles rock nightclub, in which Stradlin allegedly harassed and assaulted Neil's wife, Sharise. Following the Video Music Awards, Neil and Rose traded insults and challenges for confrontations through the press for a number of months. The duel never happened; each singer accused the other of backing out.

The song "Bastard" from the album "Shout at the Devil" was written for the band's manager at that time.
