The Mother of all Benefit songs
this one started it all folks.
USA for Africa (United Support of Artists for Africa), was the name under which forty-five predominantly U.S. artists, led by Harry Belafonte, Kenny Rogers, Michael Jackson, and Lionel Richie, recorded the hit single "We Are the World" in 1985. The song was a US and UK Number One for the collective in April of that year.
The considerable profits from the enterprise went to the USA for Africa Foundation, which used them for the relief of famine and disease in Africa; critics, however, claim that this money went directly to the (often military) governments of the affected countries rather than the people.
and now today we have songs like "Just Stand Up" and the Remake of Marvin Gaye's "Whats Going On"
