Where have you read this? It's bad news if you're right. These gigs are still listed on the Myspace page (which was updated today if you believe the 'last log in' date). Perhaps significantly, though, the Elbow support gig has never been listed on the Myspace page. Were tickets on sale for the Electric Ballroom?
My guess is it's because they've arranged a more lucrative US tour.
Why don't you message the band on Myspace? They read them you know, and reply quite often. Juanita has replied to me several times on various subjects.
It IS true unfortunately! I had already received my tickets for the Electric Ballroom but TicketMaster called about it today. Also, on the TM site, the Electric Ballroom and Oram Mor show as cancelled. The Bingley Festival site has a news item saying they've cancelled due to events beyond their control.
I commented on their Myspace, but didn't actually send a message, in case the cancellations are for personal, as opposed to financial, reasons. Though you're right about them answering personal messages!
