Hi, I'm Gerry Pepper from germany. English is a pretty hard language to write in, 
so go easy on me with the spelling and punktuation ;)

While I'm sure the other verions of the song found here at UG are excellent, they 
seem to not suit my stile of playing.
I thought this could be the case for some of you as well, so here is my chords based vesion.
I tune down 2 steps (to D flat) but it's singable in standart as well.
Have fun!

(Parts between |: and :| are repeated)

Chords:
Am: X02210
G:  32003X (Mind the alternative G Chord)
C:  X32010
F:  133211
Em: 022000

To get the melodie in with the chords, I play:

           
e|------------
h|--------1-3-
g|------2-----
D|----2-------
A|--0---------
E|----------3-

            
----------0-1-
--0-1---1-----
0-----0-------

----3---------

--3-1---1-3---
------2-----0-
