Everybody knows that James Blake's BBC Radio 1 show is famous for its host's legendary pranks (remember his 'Burial interview'?); this time Blake aired a new Jamie xx song, 'Girl', without anybody knowing - actually, he introduced it as 'Bloke' from an artist called 'Simon Tallywhacker'.

'Girl' is Jamie xx's new single, due out on May 5th backed with already-revealed B-side 'Sleep Sound'. Stream it below (around the 11:08 mark).

Update: Here's the proper video/audio for you:
