Lyrics to Harrison-penned Beatles' Classic on the Block

Handwritten "Guitar" lyrics include omitted lines

The original handwritten lyrics to the Beatles classic "While My Guitar Gently Weeps" will go on sale as part of a large auction of Beatleana on the block Monday in Arizona. The manuscript, penned by the late George Harrison, is expected to fetch up to $780,000 when it is put under the gavel by Barrett-Jackson as part of the auctioneer's nine-day auction event that kicks off Saturday in Scottsdale.

The manuscript includes lines not in the final version of the song, which was first recorded in 1968. The bottom of the page also features the words, "The band leader said he ain't playin' no more." It's thought to be a reference to the tense atmosphere in the Beatles' studio at the time the group was recording what came to be known as the "White" album.

It's a "really significant and rare piece of memorabilia," Neil Roberts, auction manager at Britain-based Cooper Owen, told the Associated Press. "It shows the work in progress, the message, and the thoughts behind one of the band members." Cooper Owen is partnering with Scottsdale-based Barrett-Jackson for the sale.

On sale at the Scottsdale, Arizona auction is a new score for the same song written in 2006 for the band's "Love" show performed by Cirque Du Soleil in Las Vegas.

A 1917 Brambach baby grand piano that John Lennon and Yoko Ono owned and kept at their Long Island estate in Cold Spring Harbor in the late '70s is among the other Beatles' collectibles up for grabs. The piano is believed to have been used during Lennon's composition of some of his final songs, such as "Woman" and "(Just Like) Starting Over."
