Уральская рябинушка = Uralskaya Ryabinushka a Russian song, Frisco accordion.

Not a song about Ribena, but words by poet Piiplenko (Пилипенко) about Rowan trees, love, long train journies, and all that stuff.
Here played on one of my favourite accordions, a rare Frisco model with one gorgeous swing tuned sound. I would not swap it for 10 Roland v-accordions.
