Paul McCartney may be 70, but he's no dinosaur. The former Beatle has launched an online version of his home recording studio that allows fans to remix his songs. "In 1971, Paul and [wife] Linda escaped London to their farm in Scotland," the website reads. "At the farm, Paul had a little studio put in so that he could demo, experiment and make music. That was RUDE STUDIO. Now YOU can experiment with Paul's music online at NEW RUDE STUDIO." Four tracks, including "Band on the Run," are included for remixing, and Paul says that if fans send him their remixes via Dropbox, he'll upload his favorites to SoundCloud.
