Report: Smash Mouth Singer Steve Harwell Hospitalized

The "All Star" singer was reportedly forced to cancel a concert on Thursday, Aug. 31, 2017, after experiencing a health scare.

TMZ reports Steve Harwell was doing sound check with his group, Smash Mouth, when he reportedly had difficulty breathing. After telling his tour manager that he wouldn't be able to perform, Harwell, 50, got a ride from an Uber driver and headed straight for the hospital.

Once there, hospital staff reportedly told him that he was experiencing the effects of the heart condition cardiomyopathy, which causes the heart to become enlarged. According to TMZ, cardiomyopathy can make it harder for the heart to pump enough blood throughout the body. Harwell's reportedly had the condition for two years.

According to reports, Harwell was given oxygen and IVs, as well as inhalers and steroids, since his hospital admittance.

The New Daisy Theatre, where Smash Mouth had been scheduled to perform, released a statement on Facebook after the concert's cancellation. "Due to an emergency illness with a member of the band, tonight's show is now cancelled," the post read. "We are immediately working on a reschedule date. All currently purchased tickets will apply to the new date. If you would like a refund, please reach out to your point of purchase."

Harwell is expected to be released from the hospital on Friday, Sept. 1 and to return to the stage later that night.
