Paul McCartney: Beyoncé's Beatles cover "Blackbiird" is great. Former Beatle Paul McCartney, 81, praises the cover version of his song "Blackbird" by Beyoncé, 42.

The Brit wrote on Instagram next to a photo with the American singer that he was "so happy" with this "great" new version. She added an extra "i" to the song title "BlackBiird" because the album is conceived as the second act of a trilogy.
