Muistoja Karpaateilta
Submitted here to clear up some misinformation. This is the "real" Muistoja Karpaateilta (Memories of the Carpathians). A traditional waltz from Finland. It is nothing to do with the waltz/song "Emma".

There are many recordings. Different keys and variations. Even some words floating around.
