Ono reveals why she granted Amnesty 'Imagine' permission

Yoko Ono says she finally granted permission for John Lennon's peace anthem 'Imagine' to be used for an awareness campaign after deciding she trusted the charity's intentions.

Since the ex-Beatle was murdered in 1980, Ono has turned down hundreds of requests from organisations wanting to use 'Imagine', but has now finally decided to give the OK to Amnesty International.
