Green Day cancels 2012 dates, postpones '13 start

Green Day is canceling the rest of its 2012 club schedule and is postponing the start of the 2013 arena tour.

Bass player Mike Dirnt says Billie Joe Armstrong's "well-being is our main concern" in the band's decision to clear the schedule through Feb 8.

He says in a statement Monday that Armstrong is doing well in his attempt to shake substance abuse problems that emerged publicly in September when the singer-guitarist had a profane meltdown on the stage of the iHeartRadio Music Festival in Las Vegas.

The Grammy-winning punks also moved up the release date of "Tre," the third installment in a trilogy of albums released over a period of months. The album will be released Dec. 11, more than a month ahead of schedule.
