JImmy Fallon, host of “The Tonight Show,” confessed on Monday night that he has a soft spot for a certain type of music.

“You know, 2018 has been a great year in music,” he said. “But as much as I’ve loved all the songs from this year, there’s nothing I love more than holiday music. Whenever I hear it, it just makes me want to sing.”

Suddenly Lin-Manuel Miranda appeared on stage and explained, “I appear any time someone says, ‘I want to sing.’”
