Tim McGraw says he expects to be nervous as the host of the Saturday Night Live episode airing Saturday (Nov. 22) on NBC. “So far now, it’s fun,” McGraw told CMT Insider this week during rehearsals in New York City. “I’m sure my nerves will get bundled up a little bit when the day comes, but the guys are great. All the cast and the people working on the show make it really as easy for you as they can, but there’s a certain ’scared-ness’ that comes with doing live stuff.” This is his first time hosting the comedy series. “The history that’s involved with Saturday Night Live is pretty special to be a part of,” he said. “As an artist, it’s pretty special to be on here just to sing, but to be on as host and be involved in the skits — and a lot of skits — is a pretty cool thing. You just gotta trust everybody and kinda do your thing.” McGraw’s SNL appearance coincides with the release of his new movie, Four Christmases, starring Vince Vaughn and Reese Witherspoon.
