This old chestnut !
Of course The Clash were and still are a Punk band.
They were there at the beginning when it happened in the UK.
Just because a band grows and changes musically doesn't cancel out who they are.
I've heard this argument so many times, by the so-called "Punk Police"
It always comes from someone who wasn't there when Punk happened.
I don't want to sound precious, but I bought their first album when it came out.
I'm a fan...and like any band they made some crap records, I won't deny that.
But when all is said and done...The Clash were a Punk band.
Cheers
