Hans Breuer is one of a kind. He was born in Vienna, Austria...to a Jewish father and a Christian mother.

He became a shepherd -- a singing shepherd.

In fact, he became a Yiddish-singing shepherd. Breuer sings to his sheep...and to his fellow Austrians.

He says his songs make the sheep happy. But they make some Austrians uncomfortable. Breuer was featured in the book "Shlepping through the Alps," by American Sam Apple.

Matthew Brunwasser schlepped along with Breuer and his 900 sheep in the Austrian Alps.
