Goo Goo Dolls singer hospitalized with pneumonia; band cancels concerts in South Africa

Wearing a blue medical gown and black Herschel hat, the "Slide" singer apologized to fans for having to postpone the shows in a video captured from what appeared to be his room in a hospital.

"Hey everybody, it's John from the Goo Goo Dolls," Rzeznik said from his bed in the video posted to social media. "I'm truly sorry that I cannot be there, but I wound up going to a doctor, and I have pneumonia. And they checked me into a hospital. And I'm stuck here for a day or two.

"We're working on getting back down there as fast as we can, and I will keep you informed about that. I'm just really sorry that we couldn't do this. I apologize that this happened. We'll come down there, we'll make it up to you guys.

"Thanks for being patient."

Following his video message, updated tour dates flashed across the screen for the end of March.

On Instagram, the band posted, "We're heartbroken to postpone our South Africa shows. This country means so much to us, and we were so excited to create more memories with you. Sadly, my doctor has advised rest and recovery. Thank you for your understanding - we'll make it worth the wait when we return in March 2025!"

Since releasing their sixth studio album, "Dizzy Up the Girl" in 1998, the band has sold millions of albums worldwide and has continued to tour.
