So I Took You- Oh no! Oh My!
great song! this is my 1st time tabbing. anyway,
this is what i figured out so far and it sounds okay. hope it helps. *CAPO 1ST FRET*

 this is the opening riff that continues throughout the song.

    G   Cadd9  G   Cadd9  G   
e|---3-x-3-33(0)3-x-3-33(0)3--------------------------------------------|   D=downstroke
B|---3-x-3-33(0)3-x-3-33(0)3--------------------------------------------|   U=upstroke
G|---0-x-0-00(0)0-x-0-00(0)0--------------------------------------------|
D|---0-x-2-22(0)0-x-2-22(0)0--------------------------------------------|

E|---3-x--------3-x--------3--------------------------------------------| 
     D D U UDU  D D U UDU  D
the 0s in paranthases are the chord change back to G, but if you listen to the song it should make more sense. 
feel free to add to it.
               peace
