As you've noticed, this is the only one out there since i've been looking for 
it and couldn't find any.  hopefully, in the future subsequent ones more finely
polished will be added.  you can see the strumming pattern and how they play it at 
www.rollingstone.com.  which is a great site by the way.  
nice duet too (although without the base and drums)
Isn't this site just as good as www.tabcrawler.com?  this site might be better cause there aren't as many versions of songs and the band names are usually spelled correctly.  but tabcrawler has such a larger variety.
