And I'm sure that Damien Barber (Time Gentlemen Please - YouTube) could have put a great show together that would have matched Riverdance.
I'm a great fan of Damien, but there's a huge difference between a theatre or TV show like Riverdance, where a dozen people can fill a screen, and something that needs to look dramatic in front of a hundred thousand people in a stadium. That tends to need hundreds of participants - who by definition have much more variable skill levels - and would be something well beyond anything Damien has attempted.

However, as far as I can see, Akram Kahn has no experience of working with such a large group either.
