Verse 1：
Baby I remember when we used to laugh and cry
You were my everything， you were my world
Now you're gone， but I'll be here forever
It may be raining now but I'll be dry
Chorus：
So long， goodbye my sunshine
It's not the end of the world but it's over with you
But you left me now and I gotta go on without you
Cause you said goodbye to me
Verse 2：
Now I'm feeling like I'm on my own again
I can't believe that you're not around
I don't know what to do without you
I need you here with me
Chorus：
So long， goodbye my sunshine
It's not the end of the world but it's over with you
But you left me now and I gotta go on without you
Cause you said goodbye to me
Bridge：
I'm gonna miss you every day and night
And I hope that you don't forget about me
And if you ever come back around
I will be here forever waiting for you
Chorus：
So long， goodbye my sunshine
It's not the end of the world but it's over with you
But you left me now and I gotta go on without you
Cause you said goodbye to me
Outro：
So long， goodbye to you baby， goodbye to me baby.
