Alan Yentob introduces Imagine - Lennon: The New York Years, which uncovers John Lennon and Yoko Ono's move to New York City as Lennon sought to escape the mayhem of the Beatles era and focus on his family and private life. It was in New York that Lennon created some of his most famous work, writing most of his songs in his apartment at The Dakota on Manhattan's Upper West Side. Revealing the tumultuous life of one of the world's most famous couples as they adjusted to life in the Big Apple, the film charts the ups and downs of their creative and personal lives - including their battle against the immigration services, and Lennon's infamous 'lost weekend'. Michael Epstein's documentary also features never-before-heard studio recordings from the Double Fantasy sessions and never-before-seen outtakes from Lennon in concert and his home movies, as well as exclusive interviews with Yoko Ono and with artists who worked closely with Lennon during this period, including Elton John and photographer Bob Gruen.
