This is a fantastic song to play with a few people. 
The strumming is not the hard part, it's nailing the very deep and rich vocals. 
Either way, I think these chords are more accurate to the song. 
Listen to the song to understand the patterns. 
Also once you learn the progression for the Chorus, Verse, and Bridge you know the 
progressions for the entire song. 
=) Have fun!

You could calm a storm with your tone
And the way you sing makes the mocking bird hold

And I try to get your affection
And all I ever do is wrong

And the way you can drive a mad half mad
I won't dance around you no more
Im the only one you should smile for, yeah!

[Chorus] x 2
You never need nobody 
You never been alone
And I try to get your affection
And all I ever do is wrong

End on G
