On April 12, John tweeted , "The best thing about Beyoncé? The break in her voice on the first 'baby, love me lights out' in XO. Real and raw." On Tuesday in Adelaide, Australia, John sang a version of "XO" using only an acoustic guitar and a harmonica, and actually managed to make it sound like one of his own songs.
"XO" appears on Beyoncé's current self-titled album, which she released with no warning in December, shocking both her fans and the entire music industry.
