There are a few phrases that were difficult for me to decipher, due to the brothers' incredible blend, and also the fact they sometimes will slide between the notes - like on the "you" in the phrase "Whenever I want you". They slide into the second note.
Again, I did my best to notate the actual notes being sung in the recording. If you find anything that needs correcting, please leave a comment and let me know.
This PDF is not the complete song as some sections are repeated. If you need the whole song form, and the rest of the lyrics, please refer to the Chords & Lyrics post.
