 They were given that name in the 1970s, due to their rampant use of drugs both on and off stage, which was a "toxic" combination that almost ended their careers and their lives.To this day, they are still commonly referred to by this nickname, despite going clean and maintaining sobriety for most of the past 30 years.Their camaraderie can be viewed in several of the band's videos, such as "The Making of Pump", "Big Ones You Can Look At", and "You Gotta Move".
