My memory could fool me - I'll dig up Fournier's drum teaching method in the basement to check his biography. And I must have an interview somewhere about his New Orleans influences.
That happens to a lot of people, even some who post a pic of his drum book in the next paragraph.

That guy, btw, seems to have an early manuscript version of the book.
