一首英文歌开头是shala✀lala的是什么歌

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
