Ebbie,

I agree with Jim. I never heard Travis do the song. However, whenever I have seen the chords reported they are usually in the key of A and fairly simple. I'm only guessing, but I suspect Travis may have used Travis picking on the song. If so, he added grace notes to pick up the melody. Sometimes people indicate a new chord for each grace note. Then it can look real complicated. Perhaps that is what you saw.
