Johnnie Walker, who has died aged 79, began his career as a disc jockey in the offshore pirate radio era of the mid-1960s. He was one of four pirate DJs – the others were John Peel, Tony Blackburn and Kenny Everett – who came to symbolise that time and continued to prosper in its aftermath.
The pirate radio stations, of which the most famous was Radio Caroline, were set up on ships and disused forts in the North Sea, avoiding British regulation by broadcasting from international waters and providing pop music to a British teen market not catered for by the BBC stations of the era.
