I wondered about that too. Seems a rather hectic bit of scheduling. And also their Canadian dates supporting Coldplay clash with festivals in Germany they were down to play.
It appears that their agents are booking them in all over the place and now that the more high-profile slots playing with Coldplay and Razorlight have come up some of the other (lesser) dates will end up being scrapped. Unfortunately I think you might be disappointed. Keep us up to date.
