To create a band that gives you the feeling you are looking at one, i think the positions onstage of the members should be changed a bit. In Brixton there were 2 separate 3-person-bands onstage that had barely contact between them or with the audience.
i would say : Miranda on the left. Then Spikey facing us, Roger, Brian and Paul in centre front, and Jamie on the right. If you split the guys that were together on the left side at Brixton, they can't form their own band within "queen" on stage and i think it will improve the feeling of looking at a band as a whole?
Any other suggestions?
