I do believe it is I AM THE WALRUS…in the cacophony near the end of the song, right around the point where you hear a voice saying, “O, he’s really dead…” and another voice saying, “Service at the villa…” It all happens about the time the orchestra breaks into GREENSLEEVES. At least that’s the way I still hear in my head some 57 years later.
A tip o’ the hat to Katsushika Hokusai — known simply as “Hokusai” — and his beautiful woodblock prints, including The Great Wave.
