I'm watching Luke the Week and Me on Netflix. In the last episode of the first season (S1E8) there's a Finnish guest band who play polka music, among others. "Livin'on a Prayer" and "final countdown" was played. I can't understand the band name, can someone help me?
It would be good if you had a video clip or a picture for it. The only Finnish band I've found through the internet now is "Lordi", but they don't match your criteria.
In episode 8 of the first season Tom Gäbel is there with his band. As far as I've seen, the songs you mentioned weren't played, nor is the band Finnish. Episode 8 isn't the last episode of the season but episode 10 (and there was a best of after that). I couldn't watch episode 10, which you may mean, on the Internet and thus help you. Please check your episode details again.
