Apple's iTunes Store is announcing that John Lennon's back catalogue and a selection of video is available through the iTunes Store.

The front page of the iTunes UK service is currently announcing that back catalogue and videos featuring the much-lamented former Beatle is now available for sale.

Sixteen Lennon albums have been posted on the iTunes Store, including remastered editions of Imagine, Mind Games, Rock ‘n’ Roll, Walls and Bridges, Lennon Legend, Plastic Ono Band, Sometime in New York City and Working Class Hero - The Definitive Lennon. The albums are all optionally available in the higher-quality iTunes Plus format.

The move also sees the Lennon Legend and Acoustic collections making their worldwide digital debuts. For a limited period of 30 days, exclusive video content will be included with the albums John Lennon/Plastic Ono Band, Sometime in New York City, Walls and Bridges, Milk and Honey and the collections Anthology and Working Class Hero.

Ten Lennon music promotional videos are also available from iTunes, including video for the tracks:Imagine. Mind Games, Whatever Gets You Through The Night and Mother. The videos are also available in the DRM-free iTunes Plus format, following Apple's landmark deal with EMI.

"John would have loved the fact that his music will now be available in a format suited to a new generation of listeners," said Lennon's widow, singer and artist, Yoko Ono.

"John Lennon is one of the greatest artists of our time," said Steve Jobs, Apple's CEO. "We're thrilled to have his solo catalogue available on the iTunes Store for the first time."

News that John Lennon's material is now available online is certain to add further fuel to online music's longest-running rumour - that music from The Beatles will eventually be made available online.

Surviving band members Paul McCartney and Ringo Starr are already engaged in a digital strategy for their own recent works.

The widow of George Harrison recently added to the debate when she confirmed that all parties with an interest in music from the Beatles had agreed to make the music available legally online, though she warned this may not now emerge until next year.

In related iTunes news, live recordings taken during the recent London iTunes Festival sets from Kasabian and Amy WInehouse have now been made available through the store.
