Was fortunate enough to have gone to that gig, although it wasn't their best, sadly. The final one of the tour at the Albert Hall was far better, although it obviously lacked the inherent atmosphere of Pompeii.
If anyone's interested, saw this lot a few years ago and they were pretty good. Back here in September.
