It's no secret that John Lennon was a talented songwriter, with a career spanning decades that changed the trajectory of modern music.
The musician, together with his bandmate Paul McCartney, penned dozens of songs which have since become classics - but that isn't to say they didn't have regrets.

He said: 'Sometimes we didn't fight it if the lyric came out rather bland on some of those filler songs like "It's Only Love".
'If a lyric was really bad we'd edit it, but we weren't that fussy about it,
