The chords are right:
I played them and taught the song to our choir on last night.
I inverted some of the chords to fit what I was comfortable with.
What I played is below in Db:
Ab / Ab Bb C Eb ........searched all over couldn't find
Gb / Gb Ab Bb Db ........nobody
(repeat)
...................nobody
B / B Db Eb Gb Ab...................greater, nobody
Eb / Bb Db Eb Gb Ab................greater, nobody greater
Ab / ................than
Db / Db Eb F Ab ................you
/ Db Gb Bb, D G B, Bb Eb Ab
Db / Db Eb F Ab..........Your Name is above all names
C, Bb / Ab C Eb F........You're worthy to be praised
Ab, Gb / Gb Ab Bb Db...Mighty are the works of Your Hands
G, Ab / Ab Bb C Eb.......Mighty are the works of Your Hands
and to follow.....
How Great is Our God can be sang with the same chords:
Db / Db Eb F Ab..........How Great is our God, Sing with
C, Bb / Ab C Eb F........me, How Great is our God, All will
Ab, Gb / Gb Ab Bb Db...see, How Great, How
