As lyric sheets go, the original handwritten words to what is arguably Bob Dylan's greatest song are about as valuable as they get.
Now some of the musician's richer fans will have a chance to get their hands on his lines for Like A Rolling Stone as they go under the hammer next month at the inaugural rock'n' roll history sale at Sotheby's in New York, with an expected price of up to US$2 million ($2.3 million).
Richard Austin, head of books and manuscripts at the auction house, said: "This is the Holy Grail of rock lyrics. The release of Like A Rolling Stone irreversibly changed post-war music history."
The opening track to the album Highway 61 Revisited was released in 1965 and became Dylan's most commercially successful song. Although it reached only No 2 in the US charts, perhaps unsurprisingly it topped the 500 greatest songs of all time compiled by Rolling Stone magazine.
In an interview with Playboy in 1966, Dylan said that he had been close to quitting the music business but the song changed it all.
