I've only recently got into them, I had never heard them (except for Rock the Casbah and Should I Stay or Should I Go?) but...I've recently become obsessed.
my current favorite song is "Lost in the Supermarket" off of London Calling
They had a Clash documentary on IFC a few months ago. They filmed it before Joe died and he was handing out flyers for his new band. He went to go hand one to some lady and she basically just told him off and said that he better not touch her. I just felt bad. He's so amazing and I can't help feeling like his last years here were not that enjoyable for him. Seemed kinda depressed.
