Johnny Cash - Sam Hall Tabs

I play this song in the key of G (which is capo on 3rd fret) It sounds good. as far as I
I think the two main chords in the song are C and F in the key of G (the shapes for
chords are A and D) I think the bends are only a semi-tone. Well here it is! Give me 
views on it and I will try to improve it if it needs to be!

b= bend a semitone
/= slide up to the note
