John Lennon Time Capsules Approved by Yoko Ono

An invitation has gone out to fill three time capsules being created to mark what would have been John Lennon's 70th birthday.

Organisers plan for the capsules to contain music from the artist's post-Beatles career along with fan contributions. One will be stored at the Rock and Roll Hall of Fame in Cleveland, Ohio, with the remainder left at two so-far undisclosed locations connected to Lennon. All three will be re-opened in 30 years time on Oct. 9, 2040, to mark the centenary of his birth.

In a statement, his widow Yoko Ono expressed her support for the project. "I am delighted to support this effort to help share John's music and messages of peace and love with the children of today and tomorrow," she said. "I know that John's work, life and dreams will help inspire them to bring a better world for everyone. Children Power!"

By visiting this site, the public has until Sept. 15 to submit their own dedications, via birthday wishes, music performances and art work.

The capsules will include restored prints of his LP artwork and a newly commissioned essay on his artistic life. Organisers are also after ideas about what else the capsules should include to help preserve Lennon's legacy.
