This arrangement has a bit of Celtic flavor. in the melody. It uses the chord progression most commonly used when playing this tune in more of a bluegrass style. This one does require some position shifting. Mostly you'll be going from 1st to 2nd position. If you don't have the experience necessary to come up with your own fingerings then you should pay close attention to the suggested fingerings in the tab.
CHECK OUT THOSE LICKS!!! There's a lot of Bluegrass and Celtic flavor here. Dig in.
