I probably spent more hours listening to The Clash, than any other single band. Most of that time was spent listening to the double album set "London Calling". You can tell Fred Armisen was a great fan of the band too as he interviews them in character.

In this Funny Or Die skit Fred Armisen interviews Mick Jones and Paul Simonon of The Clash as his alter-ego "Ian Rubbish".  He goofs along with them as if he was one of their peers.  He even has a little jam at the end and you can hear those trademark Clash background vocals cutting through.  Check it out.
