Why would Conservatives want to pass the ‘Danny Boyle’ test?

So the Conservative party’s immigration minister, Damian Green MP, has introduced the idea of the ‘Danny Boyle test.’  In today’s Telegraph he argues that the Conservative party must resist ‘nostalgists promoting a better yesterday’ and that since the Olympics opening ceremony was a demonstration of ‘modern Britain’ it is therefore a ‘test’ that Conservatives must pass.
