Sherrin was a transracial adoptee, adopted by a white couple in London. His adoptive family included two born-two children and another adopted Black child.
He showed great talent for dancing at an early age and was a professional model when he was just four. He was in the London stage version of Bugsy Malone, the Royal Variety Performance, and a number of other stage and television productions: Cats, Fame, Five Guys Named Mo, Mini Pops, From the Top, Ragtime, and That's Life. But his personality became increasingly disturbed due to stress, leading to depression, drug abuse, and finally suicide.
His family has set up a foundation to help other people suffering from severe stress.
