How John Lennon's final interview could be saved after Star Wars soundtrack obscured Beatles star's voice in clip filmed just two months before his murder

Artificial intelligence (AI) has already enabled the creation of the'last Beatles song', Now and Then, which raced to the top of the charts this week. Filmmaker Peter Jackson used an AI tool called'machine audio learning' (MAL) to isolate John Lennon's voice from an old 1970s home demo. The vocal performance – rendered'crystal clear' by the AI – was then complemented by new instrumentation from Paul McCartney and Ringo Starr, along with guitar recorded by George Harrison for the song in 1995. But MAL's work may not be finished, as it could be used to salvage the last filmed interview of John Lennon, recorded less than two months before his tragic murder. Long to the frustration of fans, much of Lennon's answers to questions in the historically priceless clip are drowned out by – somewhat bizarrely – the sound of the first Star Wars movie.
