One of the lines of BS recited repeatedly by Al Sharpton the day Jackson died was that "Before Live Aid there was 'We Are The World,' " the efforts for which were led by Jackson.
Actually, if one compares apples to apples, before "We Are The World," there was 'Do They Know It's Christmas' as organized by Bob Geldof and sung by mostly British popular singers as "Band-Aid," which became "Live-Aid."
Jackson did not "originate" this idea at all, but instead repeated something already done by the Britishers, thanks to Geldof.
"Do They Know It's Christmas" was recorded on November 25, 1984 and released on December 3, 1984. "We Are the World" was recorded in January 1985 and released March 7, 1985. Live Aid was July 13, 1985
