I'm by no means an expert on this song but I played a bit of it and something didn't sound right so I thought I would add my imput and let you decide.  On Garth Brooks "Thunder Rolls" I saw that the chorus, I guess it was, went like this:

e-------------------
b-------------------
g--------7-5-7------
d--------7-5-7------
a-------------------
e-------------------
Like I said, this advice could be wrong, but I think it's actually this:

e-------------------
b-------------------
g--------7-5-7------
d--------7-5-7------
a--------5-3-5------
e-------------------
