Will Coldplay release new song(s) alongside the release of Charlie Brown Single?

^ I don't think there was ever an *official* conformation from the guys, but it was discovered at the same time and place as the instrumental for Lukas (which we know is real because you can hear Chris' muffled voice from where it bled into the guitar mic), so I think it's safe to say that it's the real deal.

Plus, it fits the description of the song that the guys gave us :)
