In this clip, Semyon Krotsh (born 1922 in Stefanesti, Romania) performs a beautiful rendition of the traditional Passover song, "Ekhod Mi Yoydeyo" (Who Knows One?) in his dialect of Loshn Koydesh.

For some of the numbers, Semyon lists all of the units in the set the first time they are mentioned: for example, he names the patriarchs, the matriarchs, the books of the Torah, and the twelve tribes. In addition to his impressive memory, Semyon is a marvelous and charming performer -- watch his warm and dynamic facial expressions as he sings.

During the war years, he escaped to the Soviet Union and was evacuated from the town of Rîbnita (Moldova) to the Caucasus region of Russia, where he worked on a kolkhoz (collective farm). From there, he was evacuated further into Azerbaijan and then drafted into the Red Army from 1942 to 1947. After the war, in 1949, Krotsh went to Kolomyya at the suggestion of a friend from the army, since it was near Romania. However, by the time he got there, the border was closed, and so he stayed in the town. AHEYM interviewed him there in 2005.
