You are the only one My one and only one Together we've had a lot of fun But what'll I do if you leave me? If someone else should come along And take your love from me Darlin', you could never know How lonely I would be You are the only one My one and only one Together we've had a lot of fun But what'll I do if you leave me? I tried to be the kinda guy You'd wanna call your own So please don't go and throw away The truest love you've known You are the only one My one and only one Together we've had a lot of fun But what'll I do if you leave me? What'll I do if you ever take your love from me? 'cause in your arms is where I always wanna be If you should ever go away My eyes would fill with tears And the heartaches I would feel Would last a thousand years You are the only one My one and only one Together we've had a lot of fun But what'll I do if you leave me? What'll I do if you leave me? What'll I do if you leave me? What'll I do if you leave me? What'll I do if you leave me?
