The original hand-written lyrics to Bob Dylan's The Times They Are A-Changin' have been sold at a New York auction for $422,500 (£267,400).
Adam Sender, a hedge fund manager and art collector, outbid five others, placing telephone bids.
The song, one of Dylan's most politically charged, was the title track of a 1964 album.
Sotheby's had initially estimated that the two-page manuscript would fetch $200,000 to $300,000.
The document contains no musical notation, and is written in pencil. Some words are crossed out and others added.
The manuscript had belonged to Dylan's friend Kevin Krown.
Mr Sender, the buyer, also owns the guitar John Lennon was playing when he met Paul McCartney.
The hand-written lyrics for A Day in the Life by the Beatles sold in June for $1.2m.
