LIVE 8: LONDON

Madonna holds Birhan Woldou, an Ethiopian woman who, as a malnourished toddler, appeared in some of the most wrenching footage of the 1984-85 famine. Her life was saved, Live 8 organizer Bob Geldof said, in part through donations from 1985's Live Aid viewers. Live 8 concerts were held in nine cities July 2, 2005, to call attention to the plight of extreme African poverty.
