There are 2 copies of the lyrics in the thread Chords Req: Kiri's Piano (James Keelaghan). I haven't compared them in detail, but I notice they have the lyrics arranged as 4 8-line verses instead of 8 4-line verses. This corresponds to the way I hear the melody, and I see it also corresponds to the chords that Backwoodsman posted.

One minor correction: "In December" not "That December".

I listened on Spotify.
