I think Liam & Andy are passionate about it still but for the Conspiracy theorists out there...I have said since Gem's unluckyness that something was not right with him in the BE camp. Cancelling the V festival was the start of it for me. Add to that Liam's love life issues, records not selling & gigs not selling out. Plus the lack ofthe right marketing.
I hope they don't split up but based on the above it wouldn't surprise me. Also might make it easier to get a reunion at some point in the future.
