The stars did their part, flocking together for the remake of Michael Jackson's do-gooding classic "We Are the World." Now it's your turn. Sing along at home if you like as you watch the video stream of the Paul Haggis-directed mega mini opus. But then click here to download the new version of the song and donate to Haiti relief. If you caught the three-minute snippet from last night's Olympics kickoff, you know you need to watch the whole enchilada. Enjoy. And give.
