Verse 1:
Yesterday, all my troubles seemed so far away
Now it looks as though they're here to stay
Oh, I believe in yesterday

Suddenly, I'm not half the man I used to be
There's a shadow hanging over me
Oh, yesterday came suddenly

Verse 2:
Why she had to go, I don't know, she wouldn't say
I said something wrong, now I long for yesterday

Chorus:
Suddenly, I'm not half the man I used to be
There's a shadow hanging over me
Oh, yesterday came suddenly

Bridge:
Mm mm mm mm mm mm mm

Verse 3:
Why she had to go, I don't know, she wouldn't say

There's a shadow hanging over me
Oh, yesterday came suddenly
