A documentary about recovering Paul McCartney's long-lost bass guitar used in his early days with The Beatles is among a number of new films being released as part of the BBC's Arena series.
The new films will celebrate 50 years of Arena, which began life as a magazine show in 1975 before later moving to standalone films, with other upcoming documentaries on the secret sketchbooks of the painter JMW Turner and the lost audio tapes of the artist LS Lowry.
The Beatle and the Bass will follow the fan-led The Lost Bass Project campaign to recover the Hofner 500/1 bass guitar, which went missing in 1972 and was used on early Beatles songs such as Twist and Shout and She Loves You.
Paul McCartney said: "I think anything that's nicked, you want back, especially if it has sentimental value. It just went off into the universe and it left us thinking, 'Where did it go? There must be an answer.'"
The film features new interviews with McCartney, his brother Mike, friend and artist Klaus Voormann, and collaborators such as Elvis Costello, as well as those involved in The Lost Bass Project, which found the instrument in the attic of a terraced house on the south coast of England.
McCartney played the bass guitar for the first time in more than 50 years in December last year during his concert at London's The O2, which also saw him bring out Beatles drummer Ringo Starr and Rolling Stones guitarist Ronnie Wood.
A release date for the new films is yet to be announced.
