Clash - Lost In The Supermarket Chords & Tabs

I'm just writing this because the chords look very confusing. Basically, you just play E 
the E form, and put the pinky on the 4th fret of the D string for the E9. Then the bass 
the chord changes to C# and then A, but the chord is always E.

INTRO
E  E9-E-E9-E
E/C#     E9/C#-E/C#-E9/C#-E/C#
E/A      E9/A-E/A-E9/A-E/A
E  E9-E-E9-E
