Before or after you know what? He was a heavy drinker with an extreme lifestyle BUT, the great equalizer probably had a hand in this untimely death.
I never heard anything about extreme lifestyles until he was sick.
During a performance with Smash Mouth in Urbana, Illinois, on August 27, 2016, Harwell collapsed on stage and was taken by ambulance to a hospital. The band completed the concert without him, with De Lisle taking over on vocals.[7]
In October 2021, the band performed at a beer and wine festival at Bethel Woods Center for the Arts in Bethel, New York, where Harwell appeared to be intoxicated, threatening audience members and performing what looked like a Nazi salute.[8][9] Following the performance, Harwell announced his retirement due to ongoing health issues.[10][11]
Harwell had struggled with alcoholism.[14] In 2013, Harwell was diagnosed with cardiomyopathy and Wernicke encephalopathy after years of alcoholism, which can affect motor functions such as speech and memory and cause heart failure. Harwell implied he retired because these problems hindered his ability to perform well.[15]
