Both written by George Harrison "Bangla Desh" and "Deep Blue" were songs intended to raise awareness for what?
Deep Blue (song):  Given the subject matter of his lyrics, "Deep Blue" also served to convey the suffering endured by the millions of refugees from war-torn Bangladesh in 1971, as sickness and disease became widespread among their makeshift camps in northern India. Bangla Desh (song):  It was released as a non-album single in July 1971, to raise awareness for the millions of refugees from the country formerly known as East Pakistan, following the 1970 Bhola cyclone and the outbreak of the Bangladesh Liberation War.
