Saw them at Brixton Academy a few years ago - don't recall exactly when (probably not selected date). Awesome gig & band - a real spiritual & worshipful experience. Sort of fusion between a full-on gig & a worship service in which the band seemed to let the people feel they knew the songs as well as the band - everyone was singing along almost all the time - simply best gig I have been to in ages (& I have seen Pink Floyd live).
The staff never said they had so many having such a good time with so little trouble either.
Light & unobtrusive (& really rather redundant on this occasion)
Brixton Academy was a terrifc venue, not too huge to be impersonal, just right for cosy but with a "big stage" feel.
