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

Why she had to go
I don't know, she wouldn't say
I said something wrong
Now I long for yesterday

Yesterday love was such an easy game to play
Now I need a place to hide away
Oh, I believe in yesterday

Why she had to go?
I don't know, she wouldn't say
I said something wrong
Now I long for yesterday

Yesterday love was such an easy game to play
Now I need a place to hide away
Oh, I believe in yesterday

In 1980, Paul explained why “Yesterday” could be described as his best song. “I like it not only because it was a big success, but because it was one of the most instinctive songs I’ve ever written.”

The song was written at 57 Wimpole Street, London, the family home of Richard and Margaret Asher where Paul was living while dating their daughter Jane Asher. He slept in a small attic room of the house that was rather cramped without too much extra room for anything, although there was one thing that did manage to get squeezed in. “I eventually got a piano of my own up in the top garret,” remembers Paul. “Very artistic. That was the piano that I fell out of bed and got the chords to ‘Yesterday’ on. I dreamed it when I was staying there.”
