Standard (EADGBE)

Well, actually as recorded it's only the root note of most of the chords. At the last F

goes F-E-D-C (D 3 - D 2 - D 0 - A 3) into the last C chords, which rings out.

River girl, she took me in

I became her best friend

She would laugh as she filled my glass of wine

 She said, "Hold on boy 'cause I can't stay long

 It's bittersweet, this river song

 So a toast to you, and I hope your journey's kind

 Singing goodbye river, I'll see you next time
