Yoko Ono remembers John Lennon on 75th birthday

Yoko Ono has remembered John Lennon on what would have been his 75th birthday.

She will switch on the Imagine Peace Tower she has created in Reykjavik, Iceland, as a tribute to the former Beatle.

Every year Yoko Ono goes to the tower of light to mark her husband's birthday and said it was a way of being "together with him".
