Seth Meyers made the jump from 'Saturday Night Live' to being the host of 'Late Night With Seth' last night on NBC. Among his first guests were former SNL co-star Amy Poehler, Vice President Joe Biden with musical guest A Great Big World.

They performed their ballad "Say Something" without Christina Aguilera on the show. In a recent interview the duo says that when they were confronted by Christina about appearing on the song they were going to give her one of the verses to sing because they felt that her powerful, belting vocal would sound perfect, but when Christina arrived in the studio it didn't go as planned. She said just press record and let me try something! They were impressed with what she added to the song, as well as they should be because the song has been number one on the Mediabase charts for the Hot AC format.
