Marjorie Guthrie told me the same thing, that Woody had hated Irving Berlin's "God Bless America" although she didn't mention anything in particular about Kate Smith's rendition. It sure doesn't sound anything like "God Bless America, does it?

His original ending for each verse was the ironical "God blessed America for me". Later, he realized that he had a better line in, "This land was made for you and me."
