Green Day have been forced to pull out of their remaining live commitments for the reminder of 2012, and early 2013, to allow singer Billie Joe Armstrong time to complete rehab. UK fans are currently unaffected by this - the band are still planning to play London's 60,000 seat Emirates Stadium on June 1st, 2013.

“Obviously the timing for this isn’t ideal, but Billie Joe’s well-being is our main concern,” said Mike Dirnt on the bands website.  “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."

The band 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.  “If we couldn’t be there to play it for you live, the least we could do was give you the next best thing.”

Armstrong checked into rehab after last months highly publicised onstage meltdown, which saw the singer rant 'I'm not fucking Justin Bieber' to bemused pop fans at the super corporate iHeart Music Festival. 

Metallica played tribute to Green Day last weekend. The band stepped up to fill in for the punk trio at the New Orleans Voodoo Music Experience Festival, and tore through 40 seconds or so of American Idiot, before switiching to their own Ride The Lightning - watch Lars and co's rendition below.
