The Prado (one of my favorite art museums!), no idea, carbonite I assume, Peru Egypt Ireland dang that's familiar and no idea, Mozart (really weird opera, not that there are a lot of really normal operas)
That's about how I felt for the four-letter cities, but I actually pulled the correct answer for Cebu from the dim recesses of my brain. I think a lot of people guessed Japan for Kano because it matches their syllable pattern, but that's not it.
When I looked them up, it was, "oh right of course!" and "huh I did not know that." Always humbling to find out about a city of 4 million people you've never heard of.

I never watched show #2, which features Timothy Olyphant and Walton Goggins, but somehow made the right guess, which helpfully "seemed right" because it has some letters in common with the singer's name.
ah, it's an excellent show (except season 5 which is merely okay)
