Sometime ago 
I was watching the leaves
Lost in that world 
In that life beneath 
The blu skin, over my head 

And sometime ago

Any a longer, any a longer 

So I'll see you some day 
Yeah I'll see you sometime, sometime, yeah

Sometime ago I was watching the leaves 
Lost in that world in that life beneath
The blu sky over my head 

And sometime ago 
I was fighting my pain
Fighting to win 
Just like it was a game 
And I tought it would never end 

But now that I'm 
Somewhere else 
Oh I came just to visit 
And I don't think I'll stay 
Any a longer 
Any a longer

So I' ll see you 
Some day, 
Yeah I' ll see you 
Some time
And 
Just like you said 
One time, 
You can go, you can go 
You can go 
I'll be fine 
Yeah, I'll be fine 
You can go, I'll be fine 
Just fine 

Sometime ago
