Here is the convention I missed... but it has MICHAEL SWAN (yeah!!!) on the panel.
Michael Swan is one of my ELT heros, a very profound thinker, and a very human and interesting person.
His "Good Grammar Book" for students, "Practical English Usage" for teachers and "How English works" are useful, concise, and practical.
There very few videos online of Swan, but here you go, here is what I found.
