What is the author's style in Anything Goes by John Barrowman?

As a self-proclaimed autobiography despite the fact that it was written by two people, Anything Goes is written as a first-person narrative of actor John Barrowman's humble beginnings and rise to fame. Barrowman portrays himself as a "regular guy" who through perseverance, naturally-gifted abilities, and confidence, was able to reach the pinnacles of theater art as a leading man in major West End productions.
