This is not a "boom-chuck" song - it has constantly changing rythmn and subtle emphasis and tune changes. I had not played the CD for years, and I had to play it a few times to start getting the feel of the song into my head. I recommend you listen to the original about 50 times before trying to learn it; I think it is worth it - a very powerful song indeed. It may be very difficult to learn from sheet music. Anyway, good luck!
