In "American on Purpose", Craig Ferguson delivers a moving and achingly funny memoir of living the American dream as he journeys from the mean streets of Glasgow, Scotland, to the entertainment capital of the world. Along the way he stumbled through several attempts to make his mark - as a punk rock musician, a modern dancer, a bouncer, a construction worker and a stand-up comedian. To numb the pain of failure, Ferguson found comfort in drugs and alcohol, addictions that eventually led to an aborted suicide attempt. (He forgot to do it when someone offered him a beer.) But his story has a happy ending: in 1993, the washed up Ferguson washed up in the United States - which, from the age of seven, he had always seen as a beacon of goodness and possibility. Finally sober, Ferguson landed a breakthrough role on the hit sitcom "The Drew Carey Show", a success that eventually led to his current starring role as the host of CBS' "The Late Late Show". By far Ferguson's greatest triumph was his decision to become a U.S. citizen, a milestone he achieved in early 2008, just before his command performance.
