This is guitar tab in the style of the words with chord names over it throughout the song. There are chord boxes at the begining, useful for a few more obscure ones or where it is ambiguous which shape/ position they want. In addition, there are a few single note bass runs set out, when these are needed to the song. An interesting selection of songs, including a fair number from the American albums, including One, Mercy Seat, I See Darkness, Rowboat and a few others. This gives extra depth and interest to some Cash clasics like Delia's Gone, Give my Love to Rose, Walk the Line, and so on. Very playable and a real step above most of what you can find for free on the web.
