"Norwegian Wood (This Bird Has Flown)" is a song by the English rock band the Beatles, written by the songwriting partnership of John Lennon and Paul McCartney, and was first released on the album Rubber Soul, on 3 December 1965. Musically influenced by the introspective lyrics of Bob Dylan, "Norwegian Wood" was a contributing factor to the Beatles' progression as complex songwriters. In addition, the recordings of studio musicians during the Help! filming sessions, and Ravi Shankar inspired lead guitarist George Harrison to incorporate the sitar into the song.
