Last year The xx did a remix of Florence and the Machine's "You Got the Love" that ended up being a semi-surprising earworm, such that they incorporated the remix into their live sets. This past weekend at Glastonbury they kicked their version of the song up a notch by inviting Florence + The Machine's Florence Welch onstage to provide her sonic booms in person. Too bad The xx can't cart Welch with them wherever they go. [Pitchfork]
