Joni Mitchell's song "River"...
General mountain dulcimer or music discussions
It's a tastefully done video. My daughter and I watched it together a few times yesterday. We both appreciate how it moves to the exact beat of the song, doesn't try to do too much by adding meaning that is not there in the audio, and how it captures the sad tenor of the lyrics. It's so nice.
My understanding is that Graham Nash had proposed to her and she declined ("I made my baby cry") leading to an end to their relationship ("I made my baby say 'Goodbye.").
Several songs on the Blue album are just so honest and personal. It feels a little awkward to know those emotional details about someone I've never met.

It sounds Celtic to me, too, but Ken may be right that there are pieces of a couple of tunes there. Part of it is a melody I know, and I may pop in in the middle of the night when I remember it's name. But I don't recognize that descending ending/turnaround.
