I just play the double notes (double notes?) before I play the song, it begins with the 7 and 8 frets on A and E, then 5 and 7, 3 and 5, 2 and 3, 0 and 1, 3 and 0, 0 and 1, then 2 and 3, then I start the song. Hope that helps im_krister.
Not sure if it’s part of the song or not, I was just goofing off.
