That Was Yesterday Foreigner 

I thought I knew you well
But all this time I could never tell
I let you get away
Haunts me every night and every day
You were the only one
The only friend that I counted on
How could I watch you walk away?
I'd give anything to have you here today
But now I stand alone with my pride
And dream that you're still by my side
But that was yesterday
I had the world in my hands
But it's not the end of my world
It's just a slight change of plans
That was yesterday
But today life goes on
No more hiding in yesterday
'Cause yesterday's gone
Ooh-ooh-ooh
Love, my love I gave it all
Thought I saw the light when I heard you call
Life that we both could share
Has deserted me, left me in despair
But now I stand alone with my pride
Fighting back the tears I never let myself cry
But that was yesterday
Love was torn from my hands
But it's not the end of my world
It's just a little hard to understand
That was yesterday
But today life goes on
You won't find me in yesterday's world
Now yesterday's gone
Goodbye yesterday
Now it's over and done
Still I hope somewhere deep in your heart
Yesterday will live on
Ooh-ooh-ooh
