The Clash-London Calling

 So many people seem to think there is a C chord in London Calling and there
 simply is not. It is the bass that plays the C (Which is the 5th instead of
 the root) while the guitar is playing the F. Once you start banging out the
 chords your ears should sort everything out. Please message me if you have
 any questions - Gharms85

This is the main rhythm guitar that is loudest in the mix.
