John Lennon's widow unveils plaque at home they shared in London

The blue English Heritage plaque adorns a Georgian row house at 34 Montagu Square, where the couple lived in 1968.

The ground floor and basement apartment was home to several rock legends, including fellow band members Ringo Starr and Paul McCartney.

When Lennon and Ono moved in it was the first home that they shared together.

They lived at the basement and ground floor flat in the latter half of 1968, during which time Lennon was creatively very active, working on The Beatles' White Album as well as early collaborations with Ono.

It was the setting for the nude photo of the couple on the cover of their Two Virgins album.

Ono said yesterday that she was honoured by the decision to erect the plaque, one of hundreds across London marking the homes of prominent figures. The flat forms part of a Grade II listed terraced house, built about 1810-11.

The apartment has multiple Beatles associations - it was bought in 1965 by Ringo Starr, who lived there in October of that year, and later briefly tenanted by Paul McCartney and Jimi Hendrix in turn before Lennon and Ono moved in.

Ono said: "I am very honoured to unveil this blue plaque and thank English Heritage for honouring John in this way. This particular flat has many memories for me and is a very interesting part of our history."

Lennon lived at a number of addresses in London and the surrounding area between 1963 and 1971, but 34 Montagu Square is his longest residential connection with a surviving building in the capital.

Earlier this month, a sculpture was unveiled in Liverpool celebrating the life of John Lennon.

The monument designed to promote world peace was revealed at a ceremony in the late Beatle's home town of Liverpool by his first wife, Cynthia, and their son Julian.

The pair cut a white ribbon to reveal a colourful sculpture with symbols of peace. At the top of the monument a dove holds a feather in its beak, and below it multicoloured hands reach to the skies, cradling more birds.

Cynthia, 71, who met Lennon at Liverpool Art College, told people not to be sad, but to enjoy his life.

She said: "I think the mourning is over for John. I think it's time to celebrate, which is what we're doing.

"Think about his life that was positive and good and just enjoy that. Don't be morbid, enjoy the joy that he had and what we all have from his music."

The former Beatle, who was gunned down in New York City in 1980, would have been 70 earlier this month.
