Keith was born in Sandwich and was a chorister at Canterbury Cathedral. He trained in catering, then joined the Merchant Navy but illness brought him home and he started work in the advertising department of Granada Television in London. Keith was involved with British offshore radio from its very earliest days and in 1960 met John Thompson, a journalist who planned to launch Britain’s first offshore station, to be called GBLN (after his wife Ellen). Keith, along with Roger Gomez, recorded various programmes for the station but the project never materialised. Thompson later helped launch Radio Invicta and King Radio. In 1964, Keith joined Radio Atlanta, staying on as the station changed into Radio Caroline South. He left the ship in December that year but continued to work for the station on land. He returned to the Mi Amigo for a brief stint the following Easter.
While with Caroline, he put together the tribute to Winston Churchill, presented by Simon Dee, which was broadcast on the day of Churchill’s funeral in January 1965. He also worked at ABC Television, the North and Midlands weekend contractor, until 1968, as an in-vision continuity announcer, but also found time to broadcast on Radio 390 under the name Gary Courtney, from the forts on the Whitstable coast. Following his pirate days, Keith was involved with the Local Radio Association’s successful campaign to introduce commercial radio to Britain. He has worked for a number of broadcasters both in the UK and Canada, both seen and heard on the British Forces (BFBS) network and lectured on various aspects of the media.
