The parts that I've tabbed for this song, it doesn't matter whether or not you're in Drop D, which most KT songs are. I havent tabbed the chords. Most of the instrumental melodies are for bass though so someone playing this could get away with just what I've tabbed.

You repeat this through the whole song, then this is played on a 
second guitar in the second verse, "you're so pretty"
