Agree completely. Coldplay aren't my thing either and I would have liked to have seen other bands represented, but still an amazing spectacle to finish the games.
We went to the games this week and saw the swimming, basketball and a bit of the wheelchair rugby.
It was utterly fantastic and also, as you say, very humbling.
I hope the entire event will result in a noticeable change in attitudes towards the disabled and an increase in the facilities available to both the disabled and able bodied potential athletes.
