John Hockenberry reports on his week in London, where he participated in a week-long "job swap" with Dan Damon from the BBC. Hockenberry reports on the preparations being made for the Summer Olympics and the Queen's 60th Anniversary Diamond Jubilee celebration, the London Underground and more. Hockenberry also enjoyed a break from the U.S. primary. "At one point I heard something about Rick Santorum's sweater vests on the air and thought, I'm really happy to be away," Hockenberry said.
