John Larkin - a fast-living, hard-playing, stuttering jazz pianist - overcame abuse, addiction, ageism, and obscurity to stage one of the most improbable debuts in pop music history by turning his greatest pain into his purpose.

At 52, Larkin was a recovering alcoholic and veteran pianist, haunted by shame because of his lifelong stutter. His stutter meant he could scat-sing better than anyone else on the planet, grabbing and firing syllables like bullets - yet he couldn't even say his own name. But when a small, indie record label took a gamble on an oddball fusion of John's scat-singing and dance music, his life changed overnight: Scatman John was born. In 1995, his singles "Scatman (Ski-Ba-Bop-Ba-Dop-Bop)" and "Scatman's World" shot to #1 across Europe and Asia, turning a man who'd spent his life hiding into a global star. Audiences were captivated by the absurdity and charm of a middle-aged man in a fedora, machine-gunning syllables over a dance beat. But behind the novelty was a deeper story: John's scat-singing was creative camouflage for his stutter - his music, a last-ditch attempt to survive. When fame finally found him, he chose to reach others who felt broken or silenced, especially stutterers like him, by harnessing the one thing he was most afraid of: his voice.

Based on rare archives and interviews with those who knew him best, this authorized biography is a redemptive, deeply human story of struggle, heartbreak, and triumph. For anyone who's ever felt like an outsider, this book inspires with a powerful message: your deepest fear can become your greatest strength, and your pain can become your purpose.
