In fact, the script specified that it be pronounced “KAY-nar”: https://www.st-minutiae.com/resources/scripts/186.txt So that must have been forgotten/changed at some point, or maybe it is the auditory equivalent of “whisky” vs. “whiskey”.

Minor quibble (but then what other kind of quibble would it be):

In DS9: “The Adversary” the leader of the Breen Confederacy in the 24th Century is known as the “Autarch”.

Actually, “autarch” was the title of the Tzenkethi political leader, not that of the Breen. To my knowledge, the title of the head of state of the Breen Confederacy was never spoken (except perhaps in the form of Breen static).

Loved it.

Some amusing details:

• For Pike’s singing voice, he adopts a kind of Meatloaf/Russell-Crowe-in-Les-Miz style that is exactly the right mixture of masculine and adorable.
• The build up to the Klingon Boy Band: We know that Klingons love opera, heightened emotions, spontaneous group singing, and choreography (if you’re willing to consider martial arts a form of choreography). La’an even explicitly mentions singing old sea shanties which would seem to be an obvious way to translate the Klingons into musical form. So naturally, I was shocked that the Klingons would not immediately assimilate into their new musical reality. I even told my husband, “I can’t believe the Klingons would want this to stop!” And when it hit, everything made perfect sense.
