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..
