The late Beatles star's widow is curating this year's (13) Meltdown festival in London and to close the series of concerts she has decided to perform Double Fantasy, the final album she wrote with Lennon before his death in 1980.
The show will mark the first time Ono has ever played Double Fantasy in full during a live gig, and it is sure to be an emotionally-charged performance which Ono fears could tip her over the edge.
She tells BBC Radio 4, "I don't know (what will happen). I've no idea. It's like a dark hole now. I have no idea - I might faint, or scream, or just be there. I don't know."
Double Fantasy was released in November 1980, just three weeks before Lennon was shot dead outside his apartment in New York the following month (Dec80).
