Learning the bass line for a tune is essential, when possible. In this case it is a repeated idea moved through the I7, IV7, and V7 chords, copping this bass line can be very helpful not only because it gives you a better understanding of the tune but it sounds cool. On the second chorus I threw in some of my favorite chord voicings and incorporated some voice leading. Also notable is how I am sticking to the top four strings and avoiding the basic chord fingerings that may be a guitarists first choice.
