2019-09: About Sun King

Some interesting comments of Lennon on Sun King. The song has one word of Portuguese (which John Lennon didn't knew of, but Paul McCartney knew - because he was in Algarve in vacations and wrote the words for Yesterday there during the trip from Lisbon):

2016-03-22: Regarding I Want You lyrics (JL)

When you’re drowning you don’t say ‘I would be incredibly pleased if someone would have the foresight to notice me drowning and come and help me’ – you just scream!

John Lennon on the lyrics of "I Want You". The link below has also good insights on why this music ends like irt does (abruptly, because Lennon told the team to cut it there). The "wind" sound comes from a Moog synthesizer.
