The song explains the title. Jr created a really cool guitar arrangement. He usually got something great in every take, but he really nailed it here. First pass and we have used that guitar part in this song ever since.
I have just one Nit-pick... post the lyric... while I love Jr's playing and it's plainly clear why you would put the guitar(delicious) in front of the vocal... your voice is still the star for me... the way you weave a melody through your work is so relaxed and conversational... and always ends up feeling like it could not have possibly been any other way... as if you only discovered it... but I've got old ears... I have to wear a hearing aid, but that ain't no disaster
