The tabs at Stratomaster.Ca are purely fans' interpretations of how the songs are played. The band themselves have nothing to do with the tab archive except to permit its existance without fear of legal entanglements such as copyright infringement. The only "official" guitar music is in the song books available at the br.com store. To the best of my knowledge none of the online tabs were taken from the books.
Your version above sounds right. Everyone has their own way of playing some of these songs I suppose. I'll post your version if you'd like.
