You are right Paul, London Calling is not even close to being a `punk` album, its too radio pop friendly, the clash made some crap albums IMO, Combat rock-tedious, Sandinista-not great but The Clash and Give em enough rope were pretty good rock n roll albums, nicely raw and aggressive sound, but not as good as Stiff Little Fingers, they were a good punk band in their own way, their first album `inflammable material` was good, self financed and totally their own product, Jake Burns is a very passionate musician and still does the job.
I have got a huge collection of `punk` vynyl, some very rare stuff, how about The Dickies, their version of Paranoid is awesome and the banana splits song is just pure joy, Black Flag, Millions of dead cops to name a few US bands, Dead Kennedys were the best of them with their great lyrics and catchy tunes, holiday in cambodia and california uber alles are brilliant songs .
The Ruts were the first band I saw live and they were very good .
So there you go, punk or `punk` has always been my main musical influence and it has contributed some fantastic and exciting music, a lot of it has actually been brilliant music, creatively as good as much more revered bands, whether you like the real punk or the more corporate rock n roll `punk` does not matter because many have had the pleasure of listening to it, any form of art is good !
Steve Jones once said;
"The difference between the Sex Pistols and The Beatles is soap and water"
A very punk statement LOL
