1. It's a strange choice U2 chose to play at Trafalgar Sq rather than with their 'peers' at the awards ceremony, any reason for not doing so?
  2. MTV audience is not really a U2 audience, full of Bieber fans etc. U2 works much better in a setting like on a public square

    However, this question better fits in one of the existing topics like promo tour, Trafalgal performance.
