The author explained how the book celebrates Lennon’s music composition that year, as he shared a fact of how the star would dodge calls for a Beatles reunion.

The author said: “It will be about the making of all that great music, which he himself said was the one thing that mattered when people would talk to him about Beatles reunions and all those sort of stories.

“He’d say, ‘Why are you worried about us getting back together when we have all this great music?’

“So the music is very much about the story, but there will be a kind of epilogue where we understand how the things that happened 1980, including sadly his murder, resonate beyond that moment.”
