George Harrison's previously unheard Beatles tracks are set to be released.

The music legend left behind a lot of unfinished material before his death in 2001 aged 58 and his widow Olivia and son Dhani, 37, are keen to finish the tracks together and release them in the near future for his fans to hear.

She told Billboard's Overheard column: ''There are a lot of songs that are unfinished.

''I think there's a project there. I just need time to get to it.''

It won't be the first time Dhani - an accomplished musician himself - has assisted with his father's music as he also helped to record 'My Sweet Lord' hitmaker's final album 'Brainwashed', which was released posthumously in 2002.

Meanwhile, the iconic band are also set to be the focus of a new Ron Howard film, 'The Beatles: Eight Days A Week', that covers their touring career from 1962 to 1966.

The film is set for release in September 2016.

This won't be the first time fans will be treated to tracks from George as he also appears on Eric Clapton's LP 'I Still Do' on a song called 'I Will Be There'.

Before the record's release, the tracklisting showed a credit to L'Angelo Misterioso - which was the pseudonym the musician used when he played guitar on Clapton's song 'Badge', which featured on Cream's 'Goodbye'.

Harrison and Clapton were close friends in the 60s and the singer even featured on The Beatles' 'White Album' in 1968, providing the solo to 'While My Guitar Gently Weeps'.
