Good Soldier Schweik, all of that is taken as understood. Never anywhere have I said that only certain voicings of these chords should be used, only that, in order to keep the feel of the mode, the chords be made of only of notes from the modal scale itself, One can, of course, go wild, but then the feeling of the mode is lost.

Music theory is not an aggregate of hard and fast rules, it consists of observations of what musicians have done over the centuries, with guidelines (suggestions) as to what works and what doesn't.

Some of the things that haven't worked, might, if applied in different situations.

By the way, the version of John Riley that you linked to on YouTube has an entirely different tune from the version I'm using as an example. Here's the one I'm talking about, sung by Judy Collins. A note or two different and she plays with the tune a bit, but not enough to take it out of Dorian mode:    CLICKY.

P. S. I'll be gone for the rest of the day. Things to do.
