This next section is strumming around an Am at the first position and
either lifting the first finger off to form Asus2 (002200) or adding the 4th
finger on the second string third  fret  to  form Asus4 (002230).  These are
all eighth notes with no rests, but  the  chord change comes on the 4th note
of each measure (the 'and' of the second beat) like:
Strum: Asus2 Am        Asus4 Am        Asus2 Am        Asus4 Am
       |     |

Intro:
3/4 time rubato, that is, played slowly 'with feeling'.  Actually,
everyone wants to play it just like Mason does on the record...

Main Rart:
Up-tempo 4/4 time.  The signature riff makes this song and the sheet
music doesn't give a clue about how to play it.

Thumb and two fingers are probably needed at a minimum.  In the first
bar, the thumb plays the A and D string notes. In the next two bars,
the thumb plays the E string notes, and in the fourth bar, it plays
the A and D string notes.

For the first measure, finger a normal Am chord.  I find it works
well in the third measure to alternate the 2-0-2 on the G string
between the index and middle finger (play the B string notes with
your middle finger, the first G string note with your index, the
second G string note with you middle finger again, and the next G
string note with your index finger again.  (just a suggestion).
