Green Day's Billie Joe Armstrong.

The members of Green Day said on Monday they will return to the road in March after the punk rock band canceled its fall club tour and postponed later dates as frontman Billie Joe Armstrong underwent treatment for substance abuse.

"We want to thank everyone for hanging in with us for the last few months," the band members said in a statement on their website. "We are very excited to hit the road and see all of you again, though we regret having to cancel more shows."

Armstrong, lead singer and guitarist for the Grammy-winning rock band, sought substance abuse treatment in September following an angry, guitar-smashing on-stage outburst in Las Vegas. The details of his addiction were never specified.

Armstrong, 40, added to the website posting with a note on Instagram, saying:

"Dear friends ... I just want to thank you all for the love and support you've shown for the past few months. Believe me, it hasn't gone unnoticed and I'm eternally grateful to have such an amazing set of friends and family.

"I'm getting better every day," he said. "So now, without further ado, the show must go on. We can't wait to get on the road and live out loud! Our passion has only grown stronger."

The tour will begin in Chicago on March 28, with dates in Pittsburgh, New York, Toronto and other cities up through April 12 in Quebec City.

The band said it would announce additional West Coast dates in early 2013.

Tickets for the postponed shows will be honored at the new dates, Green Day said. Tickets for canceled shows will be refunded at the point of purchase. 

In November the band moved up the release date of "iTré!," part of an ambitious trilogy of albums that marks their first collection of new music since 2009, to December 11 from its original date of January 15, in part to make up for the canceled and postponed dates.

The California-based punk rock band, formed in the late 1980s, has sold more than 65 million records worldwide and won five Grammys, including best alternative album for its 1994 major-label debut, "Dookie," and best rock album for "American Idiot" and "21st Century Breakdown."

Green Day have canceled the rest of their concerts scheduled for 2012 and have postponed 2013 shows in January and early February while singer Billie Joe Armstrong continues treatment for substance abuse. After withdrawing from the Voodoo Music Experience last weekend in New Orleans, the band has nixed dates starting with a November 26th gig in Seattle through their December 10th show in Tempe, Arizona. The rockers have postponed 2013 tour dates from their January 7th show in Green Bay, Wisconsin, through their February 8th show in Las Vegas.

Green Day bassist: Billie Joe Armstrong's rehab stint 'killing everyone'

"Obviously the timing for this isn't ideal, but Billie Joe's well-being is our main concern," bassist Mike Dirnt said in a statement that also announced that Green Day have moved up the release date for "¡Tré!," the last installment of an albums trilogy. "We feel bad we have to delay our tour, so to make up for it we want to give our fans the music earlier than we had planned," drummer Tré Cool said. "If we couldn't be there to play it for you live, the least we could do was give you the next best thing."

"¡Tré!" will now come out December 11th, instead of January 15th. ¡Dos! is still set for a November 13th release.

Billie Joe Armstrong has checked into rehab just two days after his onstage meltdown at the iHeartRadio music festival Friday.

"Green Day's Billie Joe Armstrong is seeking treatment for substance abuse," his rep told E! News Sunday. "Green Day would like everyone to know that their set was not cut short by Clear Channel and to apologize to those they offended at the iHeartRadio Festival in Las Vegas. The band regretfully must postpone some of their upcoming promotional appearances."

Green Day frontman Billie Joe Armstrong returns to Los Angeles after being hospitalized in Italy

The 40-year-old rocker went on a profanity-laden rant on Friday, flipping off the camera and smashing his guitar after the band's set was supposedly cut short to give more performance time to Usher and Rihanna.

Upon noticing a one-minute warning sign in the back of the arena, Armstrong stopped singing. "You've gotta be f--king kidding me! You're f--king kidding me. What the f--k! I'm not f--king Justin Bieber, you motherf--kers," he yelled. "I got one minute--one minute left."

The musician was previously hospitalized in Italy at the beginning of September for an undisclosed illness.
