This video is from the 1980s incarnation of Radio Caroline, their ship Ross Revenge is still around and Caroline operates it as a licensed station (set to be among the last of the British AM stations) although she's in urgent need of dry-docking and repairs. There's a lot of HN worthy aspects of the story, not least in the technical challenges of operating multiple medium wave transmissions in the harsh marine environment.
