"God Bless America" is an American patriotic song written by Irving Berlin during World War 1 in 1918 and revised by him in the run up to World War 2 in 1938. Lyrics : God bless America, land that I love, Stand beside her and guide her Through the night with a light from above; From the mountains, to the prairies, To the oceans white with foam, God bless America, my home, sweet home. God bless America, my home, sweet home.
