Do you remember USA for Africa?
(United Support of Artists for Africa), was the name under which forty-five predominantly U.S. artists, led by Harry Belafonte, Stevie Wonder, 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 and specifically to 1984–1985 famine in EthiopiaAnd you can also catch Do They Know It's Christmas if you're in the mood for some reminiscing.
