Jay-Z will now be performing on Thursday July 3rd (perhaps as a warm-up for his Glasto set later that month), the same day as Hot Chip, Mark Ronson, Roisin Murphy (pictured) and Hercules and Love Affair.

The other 'dance day' will be on Saturday 5th July when Fatboy Slim headlines, alongside Underworld, Bootsy Collins, Robyn, Does It Offend You, Yeah?, Dans le Sac vs Scroobius Pip, Sam Sparro and The Whip.
