Joining Luke on his big day were Charles Kelley and Dave Haywood of Lady Antebellum, who helped co-write the song with Luke. Lady A's Hillary Scott, who sang backup on the hit, was not able to attend. Before the party, Luke, Charles and Dave met with reporters to talk about the song and its impact. Luke believed that the song was especially meaningful to the female audience. "It's a guy being vulnerable and that's what is endearing about it," he said. "People were calling or e-mailing us and saying that this song actually saved their marriage. I never would have believed that the song would do that." Also attending the party were Luke's parents, friend and fellow artist Keith Anderson and industry executives from the CMA and other organizations. "Do I' marks Luke's first No. 1 as an artist, though he has enjoyed a chart-topper as a co-writer on Billy Currington's "Good Directions." Luke told reporters, "To be the artist on a No. 1 is a pretty amazing experience. It's still very surreal. I think it's gonna take this day to make it finally seem real."
