"We Are the World 25 for Haiti" is a charity single recorded by the supergroup Artists for Haiti in 2010. It is a remake of the 1985 hit song "We Are the World", which was written by American musicians Michael Jackson and Lionel Richie.
In 1984, British and Irish pop stars united for the cause of Ethiopian famine relief as Band Aid. The following year, the Americans did the same as USA for Africa. This is how it happened.
