You were going through your life
There was time to play
Yesterday
But the light in your eyes did it start to fade
To fade away
No way of going back
To the way it used to be
No way of going back
For me
No way of going back
I took away your pain
Then the light left your eyes
Oh did you did you did you know
That yesterday
You'd lose that light
And will you will you will you say
That death today
Feels all right
Down down da-da duh da da da da da-da
Down down da-da duh da da da da da-da-da
Down down da-da duh da da da da da-da
Down down da-da duh da da da da da-da-da
You were going through your life
There was time to play
Yesterday
But the light in your eyes did it start to fade
To fade away
Oh will you will you will you cry
For yesterday
And feel the pain
Or will you will you will you run
To death today
And lose that light
Down down da-da duh da da da da da-da
Down down da-da duh da da da da da-da-da
Down down da-da duh da da da da da-da
Down down da-da duh da da da da da-da-da
We're all heading for an ending
And our minds are full of doubt
Look at your life
Today
When will it fade away
Will you will you will you cry
For yesterday
And feel the pain
Or will you will you will you run
To death today
And lose that light
Down down da-da duh da da da da da-da
Down down da-da duh da da da da da-da-da
Down down da-da duh da da da da da-da
Down down da-da duh da da da da da-da-da
You were going through your life there was time to play
Yesterday
But the light in your eyes did it start to fade
To fade away
