Comedian and late night tv host Craig Ferguson is writing his memoirs. HarperCollins will publish American on Purpose in the fall of 2009.

Book will follow Ferguson’s journey from a small town in Scotland to the U.S., with stops along the way as a punk rocker, a dancer, a bouncer and a construction worker. Host will also elaborate on his battles with drugs and alcohol — addictions he’s frequently discussed on “Late Late Show with Craig Ferguson” — and his suicide attempts.
Ferguson cleaned up and eventually landed a role on “The Drew Carey Show,” which led to his gig on the “Late Late Show” (which he’s hosted for more than three years).

Ferguson said the book will focus on “how and why I became an American.”
