Kanye is a marmite figure - to some he is a cutting edge dangerous innovative musician, to others he is a loud-mouthed egocentric buffoon.
But one thing is sure, he has a massive following, and in keeping with its ever-cutting-edge music policy I admire Emily Eavis for booking him for the festival.
I would not watch him if I was there, but there are loads of people who did, and enjoyed it - he is seriously divisive, but that is no bad thing - so were The Rolling Stones when they started out.
God save us from living in bland musical times!
