"The Day the World Gets 'Round" is a song by English musician George Harrison, released on his 1973 album "Living in the Material World".
 Harrison was inspired to write the song following the successful Concert for Bangladesh shows, which were held in New York on 1 August 1971 as a benefit for refugees from the country formerly known as East Pakistan.
 The lyrics reflect his disappointment that such a humanitarian aid project was necessary, given the abundance of resources available across the planet, and his belief that if all individuals were more spiritually aware, there would be no suffering in the world.
 Adding to Harrison's frustration while writing the song, the aid project became embroiled in financial problems, as commercial concerns delayed the release of the "Concert for Bangladesh" album, and government tax departments failed to embrace the goodwill inherent in the venture.
