Beatles Songs With Weird Touches

Lennon's murmuring at the end of "I'm So Tired" has always seemed a
little creepy to me.  The rumor for a long time was that, when played
backwards, the mumbling became recognizable as "Paul is dead man, miss
him, miss him."
Lewisohn determined that the murmuring was actually, "Monsieur,
monsieur, how about another one?"  Most likely stoned gibberish from
Lennon.
