On which Beatles album did Paul McCartney's song 'Blackbird' appear?

Paul McCartney’s song “Blackbird” appeared on The Beatles, commonly known as the White Album.

The Beatles released the double album on 22 November 1968. “Blackbird” appears on its second disc, where it follows “Birthday” and precedes “Piggies.” Unlike many Beatles recordings, the track is essentially a solo performance: McCartney sings and plays acoustic guitar, with a metronomic foot-tapping sound adding rhythmic motion.

McCartney developed the song at his Scottish farm during a period of social tension. Its writing was influenced by the civil-rights struggle in the United States, particularly the news of racial violence and the emerging progress of the movement. The bird imagery gives the lyric a memorable surface, but the song’s emotional subject is freedom and encouragement.

Listeners sometimes confuse the album title with the band’s name. The official title is The Beatles, while “White Album” is the familiar nickname taken from its minimalist white cover. “Blackbird” was not released on Abbey Road, Revolver or Help!, and it was not issued as a contemporary Beatles single.
