Simple As It Should Be

G....................D
Put your hands to my hands
.........#...........Em
Put your knees to my knees
....................C
Put your eyes to my eyes
........D...............G
Come on baby compliment me

G.....................D
Coz I don't think that we
............*................Em
should ever feel the need to worry

..and so on...

C............D
So time will go
............G
And we may be
....*.........Em
Far apart I know
....................C
But as far as I can see
............D
This is so good
.....................G
There’s no need for change
.....*............Em
It’s alright with me
............................C
It’s as simple as it should be
D
.....Simple as it should be


that's the whole song!
U don't have to strum these chords..It sounds better and more tristan-like if u play it 
tabs..listen to the song and u'll know what I mean.
there is a lot of ways to play this song this is just an example...

G D # Em
----x-----3-3----x---------x----x-----------x-------x-----------|
----x-----3-3----x------3--x----x---3------x----0--x------------|
----x-----0-0----x---------x----x--------2--x---2--x-2----------|
-------------------------0-----0------0---1----1----------2-----|
-------2-------2-----2--------0---0-----------------------2-----|
-3--------------------------------------------------------------|

and so on... but u have o play it pretty fast and find a good rhythm that suits u.. and 
it sound's pretty cool

so u just don't be affraid to use your fingers..
listen to the music..if u know what tristan's songs are like than u'll figure it out 
and untill than strum the chords.
just play how u think is the best..
that's all!
hope it helps!
