Jimmy Fallon stopped by The Morning Mash Up to talk all things holidays, from his own “Griswold-crazy” family traditions to his new Christmas song “Wrap Me Up” with Meghan Trainor. Stream the full interview on the SiriusXM app.

When it comes to releasing new original holiday music, the one to beat is always Mariah Carey with her epic 1994 hit “All I Want for Christmas Is You” — which still climbs the charts every December. Jimmy joked, “I feel like she had a great run. We love her. But I’m ready for something else.”

Last year, Jimmy released the original Christmas song “It Was A…(Masked Christmas)” with Ariana Grande and Megan Thee Stallion. Now, he’s in the process of putting together a full “comedy holiday album for next year,” he revealed, which will include his recently-released song “Wrap Me Up.”

“Full album. It’s all originals. And nothing sounds like Mariah Carey,” Jimmy said. “I don’t even know if 70 percent of it is good. There are two or three that might be good. But it’s so interesting, when you want to write these songs, a lot of people want to do a version of Mariah Carey, and I go, ‘She did it. She crushed it. She doesn’t even do a version of hers, because she did it already. She nailed it. Do something totally different.'”

He continued, “So I had this idea. Meghan Trainor’s been a friend of the show. I said, ‘I’m working on this holiday album.’ She goes, ‘I want to be part of it. I want to do something. What’s the idea?’ And of course I had no idea.”

Jimmy then sent Meghan a voice memo (he played the original recording on The Morning Mash Up) of him free-styling what would become “Wrap Me Up.” But he had the lyrics as “wrap it up,” and it was Meghan who came up with the idea of changing it to “wrap me up,” from the point of view of a guy guessing what his girlfriend got him for Christmas.

“She’s like, ‘You’re looking at the gift. Wrap me up, ’cause I’m the gift, I’m the present, I’m the whole dang package,'” Jimmy said of Meghan’s theme for the song. After Meghan sent her own demo back, the two FaceTimed and wrote the whole song together in an hour.
