There are a batch of Leonard Cohen quizzes online. I find most unsatisfying, featuring a preponderance of questions focused on Leonard’s biography, discography/bibliography, covers, and lyrics. I have, however, (re)discovered a couple of quizzes, both published at LeonardCohenForum, that are more ambitious, challenging, and, most of all, fun.
Note: (1) The original quizzes are technically expired which reduces ones enjoyment of them not a whit and (2) while the links go to the specific sections of the post with containing the questions and answers, the discussion embedded in the other portions of the post is well worth reading as well.
