If I remember correctly...here are the basic chords of how Sam played it in his lesson...
...It was a while back when I saw his video and has been a while since I've heard the song, so some of this may be how I might play it.
Key of F
/C, /Bb,
F/C-E-A
/A, /Bb, /C,
E/Db-F-G-Bb (7)
/A,
A-G/Db-E-G (3)
D/G-C-E-->>/G-C-F (6)
C/BbDEbG
F-Eb/A-D-Eb-G
Bb-F-A/C-D-F
/D,
A-G/E-G-C
/G,
D-A-C/F, /G, /A,
G-F/D-F-Bb
/A,
B-A/B-D-G
/F,
C-Bb/C-D-G
Back to top of Verse
I'd have to listen to it again for all the changes in the chorus...I don't want to give you wrong chords, but here is the one change I remember at start of the chorus
A/F-A-C-F
/C,
Bb/F-Bb-D
C/F-A-C
D/F-Bb-D
E/E-G-Bb
F/C-F-A-C
Then it goes to the (7) chord above 7-3-6...2...Then I believe it walks to the 5...
Hope this helps...
God Bless!
