Sir Paul McCartney recently revealed plans to release a 'final' Beatles song, crafted with the aid of artificial intelligence (AI) technology. The track, likely titled 'Now And Then', originated from a 1978 demo by John Lennon, which was left unfinished due to incomplete verses and objections from band members. Over the years, McCartney expressed a persistent desire to complete the song, a wish that has now been made possible by AI advancements. The technology was employed to isolate Lennon's voice from the original recording, effectively "cleaning" the audio and allowing McCartney to use it in the new record. Developed during the production of the 'Get Back' documentary, this AI tool was able to distinguish between voices, background noise, and musical instruments, creating an unprecedented opportunity for the legendary musician to "duet" with Lennon, decades after his passing. Despite the promising application of AI in music, McCartney voiced concerns about its wider implications, describing it as "scary but exciting". This final Beatles record serves as an interesting case of technology reshaping music and legacy, inviting us to anticipate where the future may lead.
