Paul was onto something here, as the fading romance with Jane Asher was providing his writing some edge, not heretofore heard. And the song's up-tempo, bluegrass-tinged arrangement presaged the country-rock phenomenon that would follow a few years later in the Eagles, Loggins & Messina, and others.
I'm looking through you, where did you go?
I thought I knew you, what did I know?
You don't look different, but you have changed
I'm looking through you, you're not the same
Your lips are moving, I cannot hear
Your voice is soothing, but the words aren't clear
You don't sound different, I've learned the game
I'm looking through you, you're not the same
Why, tell me why, did you not treat me right?
Love has a nasty habit of disappearing overnight
