Paul McCartney’s original backing track used on Beyoncé’s “Blackbiird”

Beyoncé's latest album, Cowboy Carter, features her interpretation of The Beatles classic "Blackbird," and it turns out she took more than just inspiration from the band.

Variety has confirmed that the song, retitled "Blackbiird" for Bey's album, includes acoustic guitar and foot tapping by Paul McCartney, taken from the song's original backing track.

Credits for the Cowboy Carter were not shared until after the album's official release on Friday, March 29, and it did list McCartney as playing guitar, but a rep for the two-time Rock & Roll Hall of Famer has now confirmed that guitar contribution isn't new.

"Blackbird" originally appeared on The Beatles' self-titled 1968 double album, which is commonly known as The White Album.
