I've watched all the concerts of Coldplay and Blur (Hyde-park is my favourite) and that's really great! you are very lucky!
I haven't been to their concerts, because i live in Russia and hardly ever someone comes. Just attended U2, Travis, Snow Patrol, Cranberries concerts.
Coldplay had never come to us! That's a pity.. So this year i decided at last to see Blur in London and Coldplay in Munich! 2 my favorite legendary bands! Waaait for it very much 8)
