There's a line in the one about Monsignor Horan about "You were born in the county of green, white and red / where millions of people from famine they fled.."

And, although I haven't run across it in a song, my Mom said that while she was starving in Auschwitz, they would talk about their "dream food" and the best thing any of them could think of was a some cold leftover boiled potato... on a slice of bread.
