I had great experiences taking his courses (on zoom during the pandemic) and enjoyed his books. I do not strictly follow any of the techniques, but, I am aware of them and it makes the edits and writing easier. After the first course (I think it was his Master Class), a few participants got together (virtually on zoom) for weekly song circles. The circle is still going with some of the original members. We also created an annual (in-person), songwriting retreat (Blueberry Mtn Songwriting Weekend) near Ottawa.
I have not seen the video series posted (above) by the Youtube channel "How to write songs". But, I will have a listen as I do like their stuff too.
As far as online videos on Pat's teachings, I like this one:
Pat Pattison's master class If you like the song edits he does here, it could be worth checking out.
Cheers, and happy writing,
Chad
