Today John Lennon became the third Beatle on iTunes: Sixteen of Lennon's solo album are officially (and finally) available for download via the music service. Though some of Lennon's solo work has been available via other digital downloading services since late 2005, today marks both the iTunes and worldwide digital debut of Legend and Acoustic. Exclusive video content will be included (for a limited thirty-day period of time) with John Lennon/Plastic Ono Band, Sometime in New York City, Walls and Bridges, Milk and Honey, and the collections Anthology and Working Class Hero. "John would have loved the fact that his music will now be available in a format suited to a new generation of listeners," said Yoko Ono. With solo work by three out of the four Beatles now available on iTunes, it seems we're one step closer to the inevitable digital release of the entire Beatles catalog. In fact, an industry source tells Rolling Stone that George Harrison's solo catlog is due on iTunes by the end of 2007.
