A letter signed by all four members of the Beatles petitioning for Mick Jagger to play the lead role of Alex in the film adaptation of A Clockwork Orange has hit the auction block. Paddle8 will offer up the unique item, which carries an estimated selling price of $18,000 to $25,000. As the story goes, in February 1968, Jagger's famous friends ? including John Lennon, Paul McCartney, Ringo Starr, George Harrison, Marianne Faithfull and Anita Pallenberg, among others ? sent the autographed petition to Dr. Strangelove screenwriter Terry Southern. Jagger ? who originally bought the Clockwork rights from Burgess for $500, only to sell it for a large profit to producer Si Litvinoff ? had his own vision for A Clockwork Orange: Not only would Jagger and the Rolling Stones portray Alex and his "Droogs," the Beatles offered their services for the film's soundtrack.
