The actor is best known for his hysterical portrayal of Mr. Wilberforce Clayborne Humphries, a sales associate at Grace Brothers Department store in the British sitcom Are You Being Served? John's emotive style and comedic timing were great, and he conveyed things purely through his eyes or the use of a pause to the perfection of many funny scenes. His scenes with Dick Lucas (Trevor Bannister) and Mrs. Slocombe (Mollie Sudgen) were especially good.
John died after a long bout fighting Hepatitis A. He will be greatly missed by his long-term partner Ron Lynch, fellow comedy actors, and many fans.
