Diehard Green Day fans were disappointed over the weekend when the alt-rock band was forced to cancel a show in Bolognia, Italy.

While the band was pumped to play the show, calling it “the highlight of our tour,” Green Day  frontman Billie Joe Armstrong was hospitalized under doctor’s orders, forcing the band to cancel the highly anticipated concert on Sunday.

Armstrong’s bandmates, bassist Mike Dirnt and drummer Tre Cool, filmed a short video apology for fans, explaining why they had to cancel the show at the I-Festival.

“Hi, this is Mike and Tre from Green Day. Obviously, we apologize profusely, this is really unfortunate. Billy got rushed to the hospital last night due to illness, and the doctors don’t think it’s a good idea for him to play today. This sucks. We really, really were looking forward to playing in Bolognia. It’s the highlight of our tour,” says Dirnt.

How does Armstrong feel about it?

According to Cool, he was as upset about canceling the show as the fans were. “We’re beyond devastated. We’re as sad as you guys are. Billy is extremely upset about it,” he says in the video.  And, we’ll see you very soon.”

Green Day is set to release a trio of albums — appropriately titled ¡Uno!¡Dos! and ¡Tré! — starting Sept. 25. The band also plans to put out two documentaries featuring vintage concert footage and a behind-the-scenes look at the trilogy’s recording process.

And according to E-News, Armstrong is also on tap to join The Voice as a mentor on Christina Aguilera’s team when the show returns to NBC later this month.

In July, Armstrong said he and his family are fans of the show. “The Voice has won over viewers because it’s not molding artists, it’s just giving them a little bit of guidance and direction without giving them a complete makeover,” he said.

As for Armstrong’s illness, his bandmates did not disclose details.
