I did have belarus though, by typing brest, no idea where that came from, I typed it pretty early. I think it was my first random guess. First did a few by going down the list, but then thought it might be faster to throw some names out there. Then after naming a few I looked at the list again.
Comment regarding Norway: Baerum is not a city. Went to the source listed - Baerum is there listed as a top 5 municipality, not a city. The city list looks a tad different.
Kilkenny is generally accepted as a city when it comes to quizzing.
I would accept the quizmasters decision on Kilkenny but Drogheda should not be a correct answer here.
Class challenging quiz by the way, I have some substantial gaps in my knowledge to fill it seems :)
listed for the UK though, I thought Sheffield's (estimated) population was larger than Bristol's.
And Sheriff is the Walmart of Transnistria, in USA, the club would be something like the Walmart Kalamazoo.
For Finland please add Jyväskylä (pop 138,000).
