Green Day will postpone all scheduled appearances for the months of January and February 2013. New dates for these rescheduled shows will be announced shortly and previously purchased tickets will be honored on the new dates.

The band has cited frontman Billie Joe Armstrong's substance abuse problem and stint in rehab as reasons.

Armstrong checked into rehab for substance abuse in late September following his onstage meltdown at the iHeartRadio music festival in Las Vegas.

The band was due to stop and play Jan. 10 at the Mohegan Sun Arena at Casey Plaza in Wilkes-Barre Township.

�??Obviously the timing for this isn�??t ideal, but Billie Joe�??s well-being is our main concern,�?� said the band's bassist Mike Dirnt. �??We are happy to say that Billie Joe is doing well, and we want to thank you all for the outpouring of support and well wishes that we have received, and we can�??t wait to see you all again soon.

Green Day also announced they would move up the release date of Green Day ¡Tré! to December 11, 2012 from its original date of January 15, 2013.

�??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,�?� said Tré Cool, the band's drummer. �??If we couldn�??t be there to play it for you live, the least we could do was give you the next best thing.�?�
