This is a tab my church uses in the verse. I think it's pretty funky :)
You start the tab where I have put "" in the lyrics (these are the chords we use)  
                                  
VERSE:
D                               Bm
Who am I that you are mindful of me
              Em           D
That you hear me, when I call
D                                Bm
Is it true that you are thinking of me
         Em                     C
How you love me, it's amazing 
 
 
It sounds pretty cool with a delay on as well.
Wasn't sure about the difficulty rating, but any questions tweet me @_jowilliamson, peace out!
