Yes, and the prices were the same if not higher, for seats WAY further back.

As for the comment about General Admission tickets - it's exactly the same as people getting free upgrades.
Why should people with upper tier seats be GIVEN seats in front of me?!
I have PAID for my seat with the anticipation that they are the best in the venue. If someone pays £50, knowing they are in upper tier, that's what they should get.
Fair enough if they get better seats in that block or price group, but not if they get moved to seats 4 times more expensive.
