I don't think it's possible to improve the show.
I don't mean that from a "it's so good already" perspective, but from an energy/youthfulness perspective.

Yesterday I watched the 1995 show from Wembley on DVD. It wasn't the 3rd night "Live From London" show, but the 1st night (Friday).
Regardless of which night it was though, there was an immense amount of energy being brought out by the band as a whole.
Everyone just seemed to be "on it" and the show was perfect.

15 years on that show just doesn't work any more.
I guess it's understandable, though, especially as in 1995 Jon was younger than I am now.....

If anything, they should take 5 years off, do their own thing then come back with something to prove, rather than doing it for the sake of doing it.
