Hi, Marion, sorry I missed this earlier. The only thing I could find in a quick search was this:I was lying on the sofa in our house, listening to Yoko play Beethoven's 'Moonlight Sonata' on the piano. Suddenly, I said, 'Can you play those chords backward?' She did, and I wrote 'Because' around them. The song sounds like 'Moonlight Sonata', too. The lyrics are clear, no b*llsh*t, no imagery, no obscure references." John Lennon - Playboy - 1980
