Smash Mouth, last seen performing for hordes of maskless bikers at Sturgis last summer, quietly hired a substitute singer while Steve Harwell recovers from health issues. Fans attending Smash Mouth’s recent concerts were surprised to see Harwell replaced by… some guy who definitely wasn’t Harwell, leading many to wonder if the band had fired their longtime frontman without bothering to say anything.

No, TMZ reports, Harwell just missed a few performances due to cardiomyopathy and heart failure. In 2016, if you’ll recall, Harwell collapsed onstage and was rushed out in an ambulance, forcing the rest of the band to play “All Star” without him.

The mystery singer who’s been performing at Smash Mouth’s most recent shows is apparently just some dude that the band knows. Harwell is reportedly feeling better already and will be back with the band starting tomorrow at the Jackson Mississippi State Fair, so Eve’s 6 Max Collins is out of luck.
