Barbara Streisand joined a host of stars young and old to record the classic “We Are the World” for the Haiti relief effort. Sources said Streisand joined the marathon all-night recording session in LA on Monday and sang the line originally performed by Diana Ross: “There’s a choice we’re making.” Babs did 79 takes before Quincy Jones said from the studio, “That’s perfect.”

There’s only room for 10 solo parts and there were 85 artists. It was one of the most magnificent things I have ever seen.”
