I have a feeling this is a dream, but...Beck, Thurston Moore, the Arcade Fire, the Yeah Yeah Yeahs, Rilo Kiley, Devendra Banhart, Elvira, David Cross (!), Malcolm McLaren, Peaches, Roky Erikson, Postal Service, Sparks and others collaborate on a We Are the World style Halloween song with proceeds going to UNICEF. A link to Said the Gramaphone who has "Do They Know It's Halloween" on mp3.
