I noticed that no one had attempted to post chords for this song, so here's my meager
hopefully accurate interpretation.
--------------------------------------------------------------
There's a saltwater film on the jar of your ashes I
Threw them to sea, but a gust blew them backward and the
Sting in my eyes that you then inflicted was
Par for the course just as
When you were living
-----------------------------------------------------
And that is pretty much it. Repeat throughout the song.
Now as for the "Bah baaaaaah, Bah baaaaah" or "in-between verses" parts, I'm not sure
to play.
I've been messing around with A or A, E and D chords, and sometimes I just play the
chords.
I would say just do what feels right for you.
It sounds like the underlying piano chord is an A, so work around the A.
