Green Day’s bassist Mike Dirnt recently told Loudwire that Billie Joe Armstrong is doing well in rehab and that Billie Joe’s well-being is the main concern. He thanked their fans for all the support and said that Green Day had to cancel their planed gigs for 2012, but they will rework the schedule and hit the road in 2013. Dirnt also said they had to push up the release date of the CD “TRE!” The plan was to release it on January 15th but now expect it on store shelves on December 11th.
