Here is the beginning and ending run:
Both hands: A, C, D, F, G, F, D, C, D, F, G
Bb / C-D-F-Ab
And to add to Val's post, here is an alternate way to play "I just stopped by here to tell you":
Ab / Gb-C
A / G-Db
Bb / Ab-C-D-F I
Bb, D, D, F, G, F / just stopped by here to *hold previous chord while running bass
C / Bb-C-E-Ab tell *hit chord
ya how God is good.
