Dan + Shay took the stage at the 2019 Grammy Awards for an emotional delivery of their double-nominated hit song "Tequila." The performance took place during the televised, all-genre awards ceremony on Sunday night (Feb. 10).

Dan Smyers and Shay Mooney kept their Grammy Awards performance simple: Mooney sat at a piano while Smyers strummed an acoustic guitar. They were alone on a circular stage, backed by bright light. The duo's harmonies shined throughout the performance, which ended with Mooney hitting an incredible, long high note.

Smyers co-wrote "Tequila" with Jordan Reynolds and Nicolle Galyon. Reynolds admits that he and his co-writers didn't know the song would be such a huge hit.

"We knew that we loved the song, but there’s a lot of songs that I love that no one will ever hear," he says. We never expected it to do what it has done, so that’s been kind of a cool thing ... To see people respond to something that you love as a songwriter, that’s the biggest win."

Dan + Shay were nominated for Best Country Duo/Group Performance at the 2019 Grammy Awards, for "Tequila," and they won the honor during the pre-telecast Premiere Ceremony earlier on Sunday. The song also earned a Best Country Song nod. The nominations were the duo's first Grammys nominations, and their victory was their first Grammys win.
