There are some small differences at the beginning of the song (where, after a two-measure introduction, this figure is absent for the first two measures of the first verse) and in the instrumental section (where the figure continues throughout instead of the rests in measures seven, eight, fifteen, and sixteen). The figure in the ninth measure is repeated a number of times as a coda until the song resolves.
This part (played as written, not an octave lower) is also doubled on guitar, which is usually more prominent than the Pianet.
