Original song: Christie's curator Tom Lecky holds the 16-page notes and manuscript for singer Don McLean's American Pie at Christie's auction house in New York . “It is becoming less idyllic. I don't know whether you consider that wrong or right but it is a morality song in a sense.' It has long been known that the song about 'the day the music died' refers to February 3, 1959, when rock n' roll icon Buddy Holly and fellow singers Ritchie Valens and J.P. 'Big Bopper' Richardson died in a plane crash. The eight-minute-long song was released in 1971 and was a No. 1 U.S. hit for four weeks in 1972. McLean, 69, a longtime Maine resident, says writing the song was 'a mystical trip into his past.' Legendary singer: The original manuscript also reveals a deleted verse, which was crossed out and never recorded, where McLean, now 69, writes about music being 'reborn'. Loss: American Pie mourns the death of late-50s rock n' roll icon Buddy Holly,  who died in a plane crash on February 3 1959, aged just 22, which is what McLean refers to as 'the day music died' Tragedy: J.P. 'Big Bopper' Richardson and Ritchie Valens also died in the crash alongside Buddy Holly . The original manuscript also reveals a deleted verse, which was crossed out and never recorded, about music being 'reborn'. It includes the lines 'I dropped to my knees and there I prayed and I promised him everything I could give. 'If only he would make the music live,' according to the Telegraph. American Pie had a  revival in 2000 when Madonna covered the song to promote the soundtrack to her flop film The Next Best Thing. Despite the Queen of Pop describing the cover as 'something a certain record company executive twisted my arm into doing' in 2001, her version of American Pie became a global chart hit. Christie's New York is estimating that  the American Pie manuscript will sell for $1million to $1.5million.
