Led Zeppelin Visit David LettermanLed Zeppelin visited the David Letterman show to talk about their visit to the White House this week to receive their Kennedy Center Honors. Unfortunately (or not, depending on how you look at it), John Paul Jones, 'Mr. Les Paul' Jimmy Page, and Robert Plant decided to not tempt fate and perform. But they did talk about the reception, flying shirtless, Vikings, and Nancy Wilson’s kickin’ version of “Stairway to Heaven.” Take a look.
