Roy Castle was an English dancer, singer, comedian, actor, television presenter and musician. He was a talented jazz trumpet player, and attributed his lung cancer (of which he died) to years of passive smoking in music clubs, insisting that he had never been a smoker himself. In the final years of his life, he started the Roy Castle Lung Cancer Foundation and raised money to fund a cancer centre in Liverpool. The centre opened after his death in 1998. In the mid-1960s he starred in the BBC television show The Roy Castle Show. In 1965, he appeared in the film Dr. Who and the Daleks, playing the role of Doctor Who's first male assistant, Ian Chesterton, quite differently from the way it had been played in the original television series, and in Dr. Terror's House of Horrors as a jazz musician suffering a curse after copying voodoo tunes. From the 1970s he presented Record Breakers, a children's show. He recorded the theme song for the show himself. While presenting the show, he broke several world records himself, including Fastest tap-dancer. Playing the same tune on 43 different instruments in four minutes. He also once stood in for Bruce Forsyth hosting The Generation Game in 1975 while Forsyth was ill. Throughout his adult life Roy Castle suffered from Agoraphobia. For the greater part of his career as an entertainer he was unhindered by the condition. He prided himself on being a professional entertainer and he improvised many novel ways of managing his condition. For example, when filming Record Breakers he would arrange with the producer to have a large wicker laundry basket placed out of camera shot, into which he would dive to take refuge from his panic attacks. His co-host Cheryl Baker would often sit on the basket, thus providing Roy with the comforting knowledge that the lid could not be accidentally removed. He was married to the dancer Fiona Dickson from 1963 until his death. They had four children. Their youngest son, Ben Castle, is a successful jazz saxophonist. Roy Castle memorably refused to shake Prime Minister Margaret Thatcher's hand because of her lobbying connections with tobacco company Philip Morris
