I think this might be it
I think that the song is sung to high so I usually do it in Eb or Db but I'll post it in the key of E(off of album).
LH/RH
E/E-Ab-B Friend, there will never
Ab/Ab-B-E Be a
A/A-Db-E friend, as good to
B/B-Eb-Gb me as
Db/Db-E-Ab you, there will never
Ab/Ab-B-E be a-
A/A-Db-E -nother
B/B-Eb-Gb closer than a brother
Repeat this chord pattern for the second part of that verse.(always worth the wait, faithful as the day)
These are also the same chords for the second part that goes "you know all about me, the good and the bad....." you just have to figure out which chords fit where. But these are the same ones though.
Now, the part that goes "and yet you remain, faithful to say..." I would simply play this:
C/C-E-G and yet you remaiiiin
D/D-Gb-A (fill in)
C/C-E-G faithful to sa-
D/D-Gb-A -aaaaaay Im your
E/E-Ab-B friend
then continue on with the first set of chords.
Last Part:
E/E-Ab-B everytime you
Eb/Eb-Ab-B call
D/Db-Ab-b I receive your
A/A-Db-E healing
C/C-E-G everytime you
D-D-Gb-A call me
E/E-Ab-B friend.
this is a really basic version of the song. feel free to jazz it up as you wish
