Notice
Bar 29/30 (how to play those artificial harmonics):
B: Lay the index finger of your picking hand very light on the second string above the 12th fret. Then pick with the middle or ring finger from your picking hand.
G#: Fret the third string at the first fret. Then use the same technique but played above the 13th fret on the third string.
C: Fret at the first fret, second string. Make harmonic at the 13th fret.
A: Fret at the second fret, third string. Make harmonic at the 14th fret.
Bar 35-38:
Don't be to precise. This wasn't meant to be put into bars, bur to be freetime. Just play the fast things fast and the slow things slow.
