Duncan Johnson (aka Gerald Clements) is a radio DJ, who was born in Fergus, Ontario on August 17, 1938.
In his early years he joined a radio station in Swift Current, Saskatchewan. After a time at CJOC in Lethbridge, Alberta, Duncan was offered a job in Bermuda where he stayed for a year and a half.
While in London on a trip, Johnson came across a newspaper article that outlined the formation of Radio London. At first he covered for broadcasters who were on shore leave, but eventually had his own show, "London After Midnight".
