The Beatles were a dark band. "Watch it burn, ain't it good norwegian wood" . "I used to beat my women" .
"Well, I'd rather see you dead, little girl
Than to be with another man
You better keep your head, little girl
Or you won't know where I am
You better run for your life if you can, little girl
Hide your head in the sand, little girl
Catch you with another man
That's the end'a little girl
Well, you know that I'm a wicked guy
And I was born with a jealous mind
And I can't spend my whole life
Trying just to make you toe the line"
They might sound all lovey dovey when you hear them, but if you listen to the lyrics, they were dark
