To raise money for earthquake victims, a new celebrity version of "We Are the World" was recorded on February 1, 2010, and released on February 12, 2010. Over 75 musicians were involved in the remake, which was recorded in the same studio as the 1985 original. The new version features revised lyrics as well as a rap part pertaining to Haiti. Michael Jackson's younger sister Janet duets with her late brother on the track, as per a request from their mother Katherine. In the video and on the track, archive material of Michael Jackson is used from the original 1985 recording. This version is also infamous for the way Wyclef sings towards the end of the song, fluctuating his voice in a manner that sounds like, as a music writer for the San Francisco Chronicle called it, “Not unlike a cross between a fire siren and the sound of Wyclef giving himself a hernia.”
