Bob Geldof has slagged off the clash's before when mojo or Q (think it was one of them - can't remember who) did a joe strummer/clash tribute edition. He seemed to say pretty much what he said here - they were fakes and he didn't like them until London Calling.
wasn't this the band who supported viking skull a while back in moshulu? I thought they were not bad - seem to remember them sounding a bit heavier live than those songs on myspace though. Would go to see them if they came up again.
I think it was the 'less than zero' soundtrack they were on - they did iron butterfly's In-A-Gadda-Da-Vida. Not heard it, but i'm sure i saw the soundtrack in fopp a while back for about 2. Had aerosmith and danzig on it too.
