I use the minor chords - just kinda felt 'em out, rather than learned from an authorative source; pretty much as above; good song to help teach yerself 3 finger pickin; all goes fairly straightforeward except in the transition from E back to F in the middle of the chorus you just have to change the base run a little from the typical notes you'd use coming off an E in the key of Am, & it works fine.

Cheers, BK
