The band's manager had earlier said Harwell was in the final stages of liver failure and was receiving end-of-life care at his home. 

 

Harwell retired from the band in 2021 over physical and mental health issues. 

 

The musician, who struggled with alcoholism, was diagnosed with the heart ailment cardiomyopathy in 2013; and subsequently, a neurological condition that affected his memory and speech. 

 

But his final decision to leave Smash Mouth came after he appeared intoxicated at a performance in upstate New York, where he was filmed slurring his words and yelling at the audience. 

 

Smash Mouth's long-time manager Robert Hayes confirmed to US media on 3 September that the singer did not have long to live, and was being cared for by his fiancée and hospice care.
