Pirate radio fans have been marking the launch of Radio Caroline which began broadcasting off the Essex coast exactly 50 years ago.
It was a moment in radio which changed the course of pop - and broadcasting.
Some of the pirate DJs were in Walton-on-the-Naze for the celebrations to mark the half-centenary of Britain's first commercial radio station. Mike Liggins joined them.
