While John Lennon initially believed that this song was written for him, at the start of his relationship with Yoko Ono, in fact Paul McCartney penned this Beatles classic for Lennon’s son Julian. Originally titled ‘Hey Jules’, the song was written to comfort a young Julian as his parents divorced – and its lyrics have since brought comfort to countless others. Also written around the time of McCartney’s new relationship with Linda Eastman, it’s a song that offers encouragement, advice, and a strong belief in love – yet another famous lyric about love – it seems we can’t escape it! But Hey Jude is almost as well known for its ending – over four minutes of those famous ‘na na na’s stretch the song out to over seven minutes long, at the time making it the longest single ever to top the UK charts, giving the Beatles their biggest hit in America too.
