Okay so hello everyone. I thought this was a really great cover song and wanted to find 
the chords so I figured Id make my own. This is my own rendition of it, listening to the 
song and not watching the actual video of them playing. Enjoy!

Standard Tuning: EADGBE
Capo: 1st fret

C7:    x32310
C7/G:  3x2310
F:     133211
F*:    x3321x
F/E:   xx201x
D7:    xx0212
D7/A:  x0x212
G:     xx5433 (you can bar this and make it a g7 with an E form)
G/D:   x55433
F7:    x8786x
F/D:   xx0210

usually with each chord you pluck the base note then the one a string directly below it; 
for instance, the C7 & C7/G is really playing a C7 and alternating between plucking the 
C and G below it before strumming.
