1. Both John and Luther Capo the 1st fret, so the song is in the Key of F not E.
2. I never seen the Solo played where you play it. They play it starting around the 8th or 9th fret; not starting on the 12ft fret as your lesson shows.
The Boom-Chick-a-Boom thing could be a lesson in itself. I have a hard time getting it correct.
Other than the above, good lesson.
