As world leaders descend on New York for the annual talk fest known as the UN General Assembly, some celebrities are joining them to promote their cause. Take for instance Irish rockers Bob Geldof and Bono. They are working the crowds to promote more aid and investment in Africa and call themselves "the Mutt and Jeff show".

Bono is also taking the time to meet Republican Vice Presidential hopeful Sarah Palin. He told NPR, "we are meeting wearing my ONE campaign hat. We are asking both parties not to play politics with the poorest of the poor." Geldof said they are "wholly bipartisan", though he quickly pointed out that he thinks all politicians are wankers. Geldof said he would shake hands with "the devil on the left and the devil on the right to get to the people you need to get to." A spokesman for the ONE Campaign, which promotes development aid, said only Bono, not Geldof, would be meeting with Palin.

The two musicians also spoke at the European Commission's office, where they backed EU Commission President Jose Manuel Barroso's efforts to take unused European farm subsidies to buy seeds and fertilizers for African farmers. Bono said, "these African farmers who are just scratching in the dirt, with no fertilizer, with no seeds to plant, are in a chronic state while European farmers, who of course, have solidarity with African farmers, know that there's surplus that's there for them when the bottom falls out of the European market." The U2 lead singer warned, "This is the planting season ... so we have to act fast."
