This is just a way to play the fingerpicking part that the other
versions don't include.
They're correct with the chord progression (which I will list here),
but it doesn't
sense to play the fingerpicking that is tabbed out in the other
versions.
The fingerpicking that repeats throughout most of the song is this:
e|-----------------------------------|
B|-----------------------------------|
G|-----0-----0---------7-----7-------|
D|---9-----9-----0---0-----0-----0---|
A|-7-----7-----7---9-----9-----9-----|
E|-----------------------------------|
e|-----------------------------------|
B|-----------------------------------|
G|-----------------------------------|
D|-----0-----0---0-----0-----0---0---|
A|---9-----9---------9-----9---------|
E|-7-----7-----7---8-----8-----8-----|
You can also play it like this (the second part is the same):
e|-------------------------------------|
B|-------------------------------------|
G|-----0-----0----------7-----7--------|
D|---9-----9----------0-----0----0-----|
A|-7-----7-----7----9-----9-----9------|
E|---------------10--------------------|
e|-----------------------------------|
B|-----------------------------------|
G|-----------------------------------|
D|-----0-----0---0-----0-----0---0---|
A|---9-----9---------9-----9---------|
E|-7-----7-----7---8-----8-----8-----|
