I had a clear view of what was goin on with this when i saw them in 2003 on the Bounce tour in Wolverhampton...

Basically it is only available to people with the Gold Cirlce tickets...and you simply have to join a que (ther is one either side of the stage) and then they simply let around 20 people in from each que every so often...the only down side to it is it looked like u couldnt actually see the stage where u had to que from as it was on the sides where u had to que like.....it didnt look like it was perticularly busy though...u wouldnt have to like miss loads of songs to be able to go in...maybe just 1 or 2 and u'd get in...
