Zac Brown, Julianne Hough and Sugarland's Jennifer Nettles and Kristian Bush were among the 81 artists from a wide range of musical genres contributing to Monday's (Feb. 1) recording session for "We Are the World -- 25 for Haiti." Sales of the recording will benefit earthquake relief efforts in Haiti. The song is an updated version of the 1985 recording of "We Are the World" written by Michael Jackson and Lionel Richie. During a press conference prior to the recording session in Los Angeles, Quincy Jones, who produced the original record, said he and Richie had resisted calling attention to the 25th anniversary of the all-star recording but changed his mind when the magnitude 7 earthquake struck Haiti on Jan. 12. "We got a text message saying, 'Coincidence is God's way of staying anonymous,'" Jones said. Others participating in the session included Miley Cyrus, Jeff Bridges, Barbra Streisand, Tony Bennett, Celine Dion, the Jonas Brothers, Pink, Brian Wilson, Jamie Foxx, Carlos Santana, T-Pain, Jason Mraz, Gladys Knight, Snoop Dogg, LL Cool J and Ann and Nancy Wilson of Heart.
