Thought I would post this chord structure as done by Oscar Isaacs in Inside Llewyn Davis. I think it was based on the Bothy Band version.

Queen (G)Jane lay in labor
full nine (Am)days or (G)more
'Til her (Am)women (D)grew so (G)tired,(D)
they(G) could no(Am) longer(B) there(C)
They (G)could no (C)longer (G)there

He also plays a short intro with the G sliding up to a Cadd9 position D at the 4th fret, and back down to the natural Cadd9, and then returning to the G to begin the song. Also, in the fourth line, the B chord is not fully played, but the A string plucked in the second fret in passing.
