I love this song and the lesson is clear but one suggestion if I may. A pause as your asking us practice a measure would be helpful.
For example when you you say ‘lets practice measure 14 together’ and you immediately start playing it, and then ‘one more time’ and immediately start playing it, I’ve found I’m always a note or two behind you trying to catch up.
Maybe something like, ‘ok lets do that measure together, 1,2,3…’ and then start playing. Then the student will know exactly when your going to hit the first note and start with you.
