Last week, Now and Then – which was called the final Beatles song – was released and is expected to hit UK No 1 in the singles chart.
The Lord of the Rings director also helmed the Now and Then music video which ended with a bow from the Fab Four on The Ed Sullivan Show before they faded away.
Yet despite this goodbye, it may not be the end. After all, there’s much from over 60 houses of footage and 150 hours of audio of the Let It Be sessions that remain unused.
Speaking with The Sunday Times on the prospect of even more new Beatles songs, Jackson said: “It did cross my mind!
“We can take a performance from Get Back, separate John and George, and then have Paul and Ringo add a chorus or harmonies.
“You might end up with a decent song but I haven’t had conversations with Paul about that. It’s fanboy stuff, but certainly conceivable.”
