I found this text of an unnamed hymn in A Home on the Field an exciting nonfiction book about Mexican agricultural workers in chicken plants in North Carolina - much to say about immigration policy and the power of sport (soccer in this case) to unite people. But for now I'll just shre the verse, which speaks so strongly against nationalism. Instead of "God Bless America" - or at lest in addition.
My country's skies are bluer than the ocean.
And sunlit beams on cloverleaf and pine;
But other lands have sunlight, too, and clover,
And skies are everywhere as blue as mine.
O hear my song, thou God of all nations,
A song of peace for their land and mine.
