I am glad that you are familiar,

and I suppose it is the Inkari song Koivu that you are referring to. I remember watching it on yle's website. Unfortunately there's no full lyrics on the Internet, only the first few verses can be found.

I like both Orvokkini and Saunavihdat, but I prefer the latter. The rhythm of Orvokkini is too straightforward, almost the exact same rhythm as "Lennä lennä leppäkerttu" and "Pieni tytön tylleröinen". I wonder why they all sound rhythmically the same. Someone once said that this is the rhythm of Kalevala, but I have no idea.

Never had a sauna in my life but I can feel the sentiment of Saunavihdat. Sometimes the coldness of the outside world is just unbearable for me.
