I knew people who would refer to this guy as Smash Mouth. They thought that was his stage name or something. Apparently though the band will keep touring without him.
source close to the band tells us ... Steve knew it was time to hang it up after the show, because it's impossible for him to keep performing as his health continues to deteriorate.
We're told he was diagnosed with cardiomyopathy 8 years ago, which has led to other medical setbacks like heart failure and Wernicke's encephalopathy ... a condition that impacts his motor functions, including speech and memory. He's also battled substance abuse over the years, which is further contributing to his health crisis.
