Two members of U2 are keeping busy outside the studio trying to help others.

Bassist Adam Clayton will once again help the Walk in My Shoes charity, which raises funds for Ireland's St. Patrick's Hospital Foundation and its mental health services for vulnerable young adults. He's working to boost awareness of the charity through a "funky shoe day" on April 12th in Ireland, in which people will be encouraged to wear unusual footwear to work or school -- and to donate to the cause. Clayton says, "'I'm happy to raise awareness and funds, and I hope everyone will join me in wearing stylish and mismatched shoes on April 12th."

Bono addressed the issue of global poverty at the Ted conference in Long Beach, California on Tuesday. Backed by a slide presentation, he said, "If you live on less than $1.25 a day, this is not just data. This is everything. If you're a parent who wants the best for your kids, and I am, this rapid transition is a route out of despair and into hope." But he remained optimistic, adding, "We're going to win [the war on poverty] because we don't understand politics. We're going to win because we don't play their dirty games. We're going to win because we don’t have an agenda. We're going to win because the tears that comes from our eyes actually come from our hearts. We're going to win because we have dreams. We're going to win because we are willing to stand up for our dreams."
