Sir Paul McCartney might work with George Harrison once more, more than 10 years after his former Beatles bandmate passed away. Harrison’s wife Olivia is working on using demo tapes and song ideas her husband developed toward a new album. “There is some more material,” Olivia told The Sag Harbor Express. “There may be a minute of something he was writing and it will never be finished. I had an idea of giving unfinished songs to different people-with one going to Paul.” Rumor has it that Eric Clapton, Tom Petty and Jeff Lynne will be involved in the album, which is planned for release in 2013.
