“FOR heaven’s sake, sit down,” pleads John Lennon’s estranged father.

“I’ve not sat down since 1962,” his son replies.

Lennon Naked (BBC4, 9:30pm tonight) is a marvellous film with another top class performance by Christopher Eccleston.

Although the one-off 90-minute drama begins in the middle of black and white Beatlemania, it mainly focuses on the years 1967 to 1971.

Including the break-up of The Beatles and John’s life changing meeting with Yoko Ono, played by Torchwood star Naoko Mori.
