I was writing about the fact that David Letterman would be honored as a Kennedy Center Honoree all the way back in September.
Today it occurred to me to check youtube to see if that video was online. It is. Here is his segment of the awards ceremony. You'll see he's next to Led Zeppelin.
People don't recognize that Conan has a very high, pretty singing voice. Now that he's down in Atlanta for a week of shows, he decided to show off that fact by joining a Gospel choir.
It's always strange when people don't understand that Conan is joking. Why would anyone take Conan at face value? I suppose they don't watch.
