I've been a fan for a relatively short time - just over 5 years. I've seen them live about 10 times and I really do think they're getting better all the time. The Forum gig in London was the best live performance of any kind that I have ever been to.
I also think Ceri has had a fantastic, energising influence on the band - obviously I know nothing about what goes on behind the scenes but he seems to fit in so well, he's an absolutely CRACKING bass player (the best I've ever seen live), and he has a wonderful energy on stage.
As for the rest of them, well, they just seem to keep reaching new highs. Every time I think they can't get any better, they do. Long may it continue.
