Yeah. The Beatles' lyrics started out so "up" "bubble-gum" and innocent. Then they progressively got darker...all kinds of weird stuff.

I used to joke that they went from "I Want to Hold Your Hand" to "Why Don't We Do It In the Road"

The ugliest love song....and it's really unfortunate because the entire song ROCKS, until you get what it's really about...is "Layla". And I really used to like Eric Clapton.
