John Mayer Takes On Beyoncé’s XO In Acoustic Cover
Having performed the song at a live show in Adelaide, Australia, Mayer then released the track on iTunes this week.
It’s no secret that John’s a fan of Queen Bey’s work, having tweeted in April: "The best thing about Beyoncé? The break in her voice on the first 'baby, love me lights out' in XO. Real and raw."
He may even get to share the track with Beyoncé’s hubby Jay Z, as he’s headlining part of the Made In America festival in August.
