Using machine learning Sir Paul said they managed to “lift” the late John Lennon’s voice and get the piece of work completed. By extracting elements of his voice from a “ropey little bit of a cassette”, the 1978 song entitled “Now and Then” will hopefully be released later this year. “We had John’s voice and a piano and he could separate them with AI. They tell the machine, ‘That’s the voice. This is a guitar. Lose the guitar’. This was not a “hard days night” and was certainly faster than “eight days a week”, it will be interesting to hear the finished result and we may be “glad all over” that they did not “let it be”.
