Previously-unheard music by George Harrison is set to be released.

The Beatles legend left behind a lot of unfinished material before his death aged 58 in 2001 and his widow Olivia and son Dhani, 37, are keen to get the tracks completed and released for his fans to hear.

Fans got to hear new music from George earlier this year as he appears on Eric Clapton's LP 'I Still Do' on a track 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 1969 album 'Goodbye'.

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

However, their friendship was effectively ended when Clapton had an affair with Harrison's wife Pattie Boyd and went on to marry her in 1979, two years after she divorced the former Beatle.

But the two music legends did eventually reconcile their relationship and became close again.
