Watch Lucy Dacus Perform ‘Best Guess,’ Officiate Weddings on ‘Kimmel’

Four couples had their first dance to the sound of Lucy Dacus‘ “Best Guess” as she performed the record on Jimmy Kimmel Live. At the end of the song, the singer-songwriter made a seamless transition to the vow portion of her appearance, where she officiated weddings for her on-stage guests.

“Hi, everyone,” Dacus said. “You ready to get married?” The couple shared promises to give themselves to each other and to care for one another in their marriage, in good times and in bad, in sickness and in health. And with that said, they sealed their union with a kiss.

“Best Guess” appears on Dacus’ latest album, Forever Is a Feeling. “It’s a song that is basically admitting that you can’t control anything, you can’t predict the future, but you can make your best guess,” she told The New York Times.

She performed the record at the New York iteration of All Things Go in September, inviting nine couples to the stage. Ordained by the Universal Life Church, she officiated at two of the marriages and signed the remaining seven wedding certificates as a witness.

“I wish it was rote and it wasn’t calling to mind any threats to people’s rights,” Dacus said about officiating marriages in the midst of our current political climate. “But I can tell it’s coming up in everyone’s mind, everyone who’s onstage, everyone in the crowd. There’s no getting around everyone wondering if this is a temporarily possible moment.”

In the caption of an Instagram post shared following the festival, Dacus wrote from the same place of optimism that colors “Best Guess.” “I am often in disbelief, disoriented, and overwhelmed,” she said, “but I am deeply in love with this life.”
