Paul McCartney and Ringo Starr, the two living members of The Beatles, have reunited for a cover of their 1970 hit Let It Be on country singer Dolly Parton's coming rock album.

Parton released the single on Friday ahead of the November debut of her album Rockstar. McCartney sang and played piano while Starr played drums on the recording.
