Tonight (Sept. 26), Green Day kick off their tour in Columbus after an illness that spread throughout their ranks forced the start to be delayed by a week. Today, they revealed that the three postponed dates in support of Revolution Radio will be tacked on to the end of the tour.

Consequence of Sound is reporting that they will now play in Chicago on Oct. 23, Detroit a day later and St. Louis on Oct. 26. A fourth concert that scheduled for last week, in Toronto, was booked as part of the World Cup of Hockey and will not be made up.

Arriving on Oct. 7, Revolution Radio is Green Day's first album since they put out three records -- ¡Uno!, ¡Dos! and ¡Tré! -- over a four-month stretch in 2012. This was in the middle of a tumultuous period for the group. On the eve of ¡Uno!'s release, singer Billie Joe Armstrong went into an expletive-filled rant after finding out that the band only had one minute left in their set. Shortly thereafter, Armstrong went into rehab for substance abuse issues, and they wound up canceling their tour. Last week, Armstrong spoke about his state of mind at the time.

“The thing about someone who’s losing their mind is that they don’t know they’re losing their mind,” he said. "I thought my life was completely normal. And it wasn’t. I was on drugs! And people aren’t acting rationally when they’re on drugs. So I had to take care of myself. I had to kick that, and I did. Then we took a long break which was totally necessary.”

So far, Green Day have previewed three songs from Revolution Radio, a collection of songs dealing with topical issues, "Bang Bang," "Still Breathing" and the title track.
