Festival invites stars perform and make aliens rise up from deep sea base

Sir Paul McCartney and Ringo Starr have been invited to perform at 'Alien Woodstock' in a bid to make extra-terrestrials reveal themselves to the planet.

The two musicians - who were joined in The Fab Four by the late John Lennon and George Harrison - are wanted by UFO expert Michael C. Luckman to play at the proposed event in Malibu, California.
