As a huge Supergrasss fan, I can say that in the past they could have been accused of simply going through the motions a couple of the times in concert. The band was great when they were young, brash, etc on that first tour of the US in support of "I Should CoCo". The second and third time there was something lacking, heck the drummer asked for a glass of white wine midset which is not a very rock n' roll moment. The last time for the singles tour, an unexpected acoustic set made for a much more entertaining show. Would have to say if you are Wu fan, and think this maybe be your chance to see them together for say the next five years, then that would get the edge.
