Absolutely agree with the OP, an iconic singer who's gone far too early.
I was coming up for my 8th birthday when Ghost Town was number 1. I absolutely loved it though didn't understand the story it told, and only really came to appreciate it a decade or so later. There are so many fantastic Specials tracks - Nite Klub, Gangsters, A Message to you Rudy, Man at C&A, Do Nothing, .... all songs with a message which really resonates. I'm sure they've played a part in shaping who I am today. and it's one of my biggest regrets that I've not seen them live.
It's depressing that despite being 40 years on from when 'Ghost Town' and 'The Lunatics' were released they're as relevant as ever.
