There is this Finnish band called Eläkeläiset that covers many past hits in the style of humppa and jenkka music with Finnish lyrics with hilarious results.
They are apparently trying to get the official Finnish selection for next year's Eurovision.

Here are some of their greatest humppa hits:
Smells like Humppa (Smells like Teen Spirit):


Rantallihumppa (Run to the Hills):


Humpatkaa (Thunderstruck):


Kulumaton humppa (Can't Get You Out Of My Head):


Paratiisihumppa (Gangsta's Paradise):


Most of their other covers can be found here:
