I do realise that some readers' eyes will glaze over at longer posts, but so be it.
I think it needs to be said that many of these Left/Right issues, and the way people feel about them, can often come down to both personal experience mixed with the dominant media perspectives of the time - which often seem to have a lasting effect, especially if they enter into the realms of 'mythology'.
Firstly, on the issue that Martin raised regarding Tony Benn and the offshore Pirate Radio stations - I would agree that they (the pirates) had a positive influence on mainstream and commercial radio, opening up what had been a very stiff and stifled area of that section of the broadcasting media. Before the Pirates launched, I can remember having to listen to Pop music on a rather weak and fluctuating signal from Radio Luxembourg, as there was no way that the BBC Light Programme or the World Service would play that type of music.
Martin's point that LBC (etc.) also would not exist had the cartel not been broken, was well made.
As Postmaster General at the time, I would suppose that Tony Benn had no option but to close down, or attempt to close down these stations that (it was said) were operating illegally, even though (as far as I know) they were anchored outside of British territorial waters.
Had there been a Conservative government at the time, presumably the action and result would have been the same - although I'm not entirely convinced of this. In my experience, support for The Arts tends to be more positive under left-of-centre governments, and less so under right-of centre ones. If anyone has any figures to disprove this, I would be happy to be proved wrong - but it's certainly my perception over sixty-odd years.
Maybe it goes to show that sometimes, a little anarchy and bucking the system, as the pirate radio stations did, can have a lasting and positive effect. Much of this nation's GDP is derived from creativity in the Arts and has an extremely positive effect on how the world sees us. This creativity needs a platform and should not be stifled. As Martin also wrote, the setting up of Radio London, and the liberation of the airwaves, was a direct result (it could be argued) of the bravery of the Pirates.
I am splitting this post into two, in order to keep them relatively short. I hope they are not too off-topic, but I just wanted to reply to a couple of points that have been made here. My next post will be about Arthur Scargill and the miners' strike. I bet you can hardly wait!
