(that way he can do all those nice bass notes). 
Intro and Verse: 
It's worth listening for the strum pattern, as JB tends to like his fast but understated strumming. 
He does a different intro on every version, so pick the one you like. Usually he just  
plays the  chord over 
and over. 
For the verse, he's playing it like this: 
Well I'll tell you a story 
About a girl named Kimberley 
Who all the cowboys wanted 
Cos she was wild and free.
