Danger Man! Not So Jolly Roger
For a start the human chameleon John Drake becomes the cool DJ Johnny Drake, or JD. How cool is that?
For another the setting is about as groovy as you could want. At the time we didn't have many licensed radio stations in the UK and the inability of the BBC stations to cater to the audience for pop music led to a proliferation of pirate radio stations. Naturally pirate radio continues, but the setting places the episode firmly in the latest trends in 1960s Britain.
Many of these stations were based off shore to take advantage of a legal loophole, but this Danger Man sets Radio Jolly Roger on the Red Sands Sea Forts in the Thames estuary. They are still there and an internet search demonstrates loads of nostalgia for their time as several pirate radio stations. That's right, the uber-cool Danger Man series recorded an episode on location at a genuine pirate radio station, Radio 390. You can see contemporary pictures of its use as a radio station here and here. This page shows more of the workings of the pirate station.
So to be honest it would be a bit difficult for this Danger Man to go wrong. One of the things I like best at fifty years' remove is the sight of a radio station which now seems so old-fashioned, dependant as it was on analogue media.
If I have a criticism it is that once Drake arrives at the sea fort it is fairly obvious what is going on. I have another criticism which is the bizarre choice of the Blue Danube Waltz to signal that they are signalling. It is completely off genre from the other music. If you like the records played on the radio station, you can find details of them here.
So despite a predictable plot, this episode of Danger Man makes up with sheer sixties chic.
