Dude, u do realize that you posted this at 5 in da morning right? Most of us probably still sleep by that time, especially on a Saturday. You don't have to keep posting the same question, give us some time to respond man.
I'm not in front of my keyboard, but I think the song is in Eb (well that's the key I play it in). This is from memory:
Eb / G-Bb-Eb He's an on time God yes He is
C / C-Eb-G on time God yes He Is
Eb / Eb-G-Bb He may not come when you want Him
C / C-Eb-G (but He'll) be there right
Bb / Bb-D-F on
Ab / Ab-C-Eb time
A / A-C-Eb
Bb / Bb-Eb-G He's an on time
Ab / Ab-C-Eb God
Bb / Ab-C-Eb yes He
Eb / G-Bb-Eb is.
That should get you started a little bit.
