The latter: I used the track without added music by default, and added the specific changes that I felt belonged soundly (pun intended).
If I had had any idea Kerr’s regular version of this project would remain unseen, I’d have kept my sources he sent. As it stands, what I have released is all I have.
I mirror your praise to Kerr and was happy to re-extend it somewhat for a version I could be cozy with.
