Intro:
Hit F

E|--1---|
B|--3---|
G|--3---|
D|--2---|
A|--1---|
E|--1---|

a few times softly, louder each time

then go to G-->Bm7

Here are a few forms of each chord

G:                 Em:

E|--3--3--3------| --0-------
B|--2--2--5------| --2-------
G|--0--0--5------| --2-------
D|--0--0--4------| --0-------
A|--0--3--3------| --0-------
E|--3--3--3------| --0-------

Bm7:
E|--2--7-----|
B|--2--9-----|
G|--4--7-----|
D|--2--7-----|
A|--3--7-----|
E|--2--7-----|

The first form of each chord seems to sound the best, but the bar G and the Bm7 at 
the 7th fret seem to be
the easiest progression to play. Fool around with the combinations and find out which works best.

Here's the song:
