as the resident clash nerd around here, I'll chime in on this one.
The US version is indeed a more rounded and cohesive record, the addition of songs like 'white man' and 'complete control' added another dimension to the record. But it's not truly their first album anymore. And my personal opinion, I'd rather have seen 'cheat' or 'protex blue' on the US version as opposed to 'jail guitar doors' which is a revved up 101ers song. good song, but not really up to par with the rest of the record.
I also much prefer the more raw mix on the UK versoin.
