From deep in the back catalogue, Cirque du Soleil draw forth Quidam for their annual Royal Albert Hall run. The show was at the RAH back in 2009, at which time it was already something like a decade old and looking a little worse for wear. If you'd like to see extremely high skills and a large cast in a splendid venue, then it might be worth it; just make sure to suspend your disbelief / critical faculties / dress sense.
