78s

...and on the singles side, we make an excursion to Rillumarei, popular music scene in 50s which came as a backlash to the accusations from the "serious art music" side that popular music was unsophisticated and low-brow...resulting to a number of artists happily embracing vulgarity and performing humorous polkas and whatnots with accordion, often mocking "culture" and "art"...

First one is one of the main performers of the scene:
Reino Helismaa: Sorsanmetsästys / Pojanpojan lättähattu

The other one is more marginal, more of a one-hit wonder:
Veikko Sato: Linjuripolkka / Rengasmatkalla
