this is my first tab but I'm pretty sure it sounds ok ;) I haven't found any tabs from red dead redemption so I thought I will try myself.
It is played from about middle of the song to the end. Listen to the song and you will know how to play it.
5 -6 5 6 5 4 -4 5 4 -4 -3
that's all I figured out for now, I will try to add more or different song from RDR :D
If you have any suggestions let me know!
