McGraw is set to perform as the musical guest on “The Tonight Show Starring Jimmy Fallon” on Feb. 19, 2014 with Bradley Cooper appearing on the same night.
Billboard reported Fallon discussed the NBC executives response to his move from "Late Night with Jimmy Fallon" to his new spot replacing Jay Leno on "The Tonight Show" by saying "No one tells me [to do] anything -- they see what we've done with our show."
Fallon added "At one point, they said I couldn't host the Emmys: 'No one will watch if you host it. You have too young of an audience.' We hosted the Emmys and did what we normally do on our show. Its ratings were up from the year before. With 'The Tonight Show,' they're kind of just letting me do it."
