Why did the singers meet in Hollywood?

Dozens of recording stars began converging on a Hollywood studio Monday to add their voices to a song they hope will raise millions of dollars for Haitian earthquake relief25. The words and music are an updated version of "We Are the World," a song that raised at least $ 30 millions for African humanitarian programs 25 years ago. Lionel Richie, who co-wrote the first song with Michael Jackson, is organizing the effort26. The original producer, Quincy Jones, is using the same studio he used in 198526. Reporters and security surrounded Henson Studios, anticipating the arrival of limousines delivering the stars Monday afternoon for what is expected to be a marathon recording session26. Smokey Robinson, who sang on the original, said the list of 100 singers asked to take part does not include any of the 45 stars from the previous version26. Organizers have not said when the song might be ready for the world to hear.
