song=\'\'\'
Trouble will find you no matter where you go, oh oh

No matter if you;re fast, no matter if you;re slow, oh oh

The eye of the storm wanna cry in the morn, oh oh

You;re fine for a while but you start to lose control

He;s there in the dark, he;s there in my heart

He waits in the wings, he;s gotta play a part

Trouble is a friend, yeah trouble is a friend of mine

Ahh..

Trouble is a friend, but trouble is a foe, oh oh

And no matter what I feed him he always seems to grow, oh oh

He sees what I see and he knows what I know, oh oh

So don;t forget as you ease on down my road

He;s there in the dark, he;s there in my heart

He waits in the wings, he;s gotta play a part

Trouble is a friend, yeah trouble is a friend of mine

So don;t be alarmed if he takes you by the arm

I roll down the window, I;m a sucker for his charm

Trouble is a friend, yeah trouble is a friend of mine

Ahh..

How I hate the way he makes me feel

And how I try to make him leave

I try, oh oh I try

He;s there in the dark, he;s there in my heart

He waits in the wings, he;s gotta play a part

Trouble is a friend, yeah trouble is a friend of mine

So don;t be alarmed if he takes you by the arm

I roll down the window, I;m a sucker for his charm

Trouble is a friend, yeah trouble is a friend of mine
