This is a very easy intro to learn. It's not all like the exact, the ending of the intro if not right, but still it's close.
 
E-------2-0------------|
B----------3-----------|
G-----2-----2----------|
D---0--------0---------|
A--------------2-3-5-5-|
E----------------------|

TIP: If u hold a D chord, it gets easier. And u just remove the finger on 2 freth E string when u need to! 

 Intro: D (E on second fret, E on 3rd fret and E on 5th fret.) 
if you like you can just pluck the 2nd, 3rd and 5th fret 
of the low E string, be sure to mute the remaining 
strings so you don't get weird out of place sounds.

D              A                G
don't tell me love is something you own't try again,
A
that's just not true...
(repeat this pattern for the verses)

Chorus:
D            A          Fm            G
i will be by your side if ever you fall deep 
in the dead of the night
A           D                  A           
whenever you call. and i won't change my mind, 
  Fm  G A
no i'll see you through
G       A (or you can play the E chord on the 3rd and 5th fret)
and i won't give up...
