One half of Brooks and Dunn, Ronnie Dunn, was at Bones and Caitlin's wedding. During the reception, he got up on stage and performed a non-traditional wedding song. Brooks and Dunn's "Neon Moon" is a very sad song, and one that many wouldn't choose to have played at their wedding. However, it's a favorite song of Bones and Caitlin so they asked Dunn to sing it at their wedding. He jumped up to do it with the wedding band and nailed all of the high notes despite his hesitation.
In the video Caitlin shared, Bones and Caitlin's own personal neon moon sign appeared during Dunn's performance. The neon sign had a sliver of a moon, some small stars, and the names 'Bobby & Caitlin' written. The moment was a big one during the wedding, as fans can see in the video that all of the wedding guests jumped at the chance to join Bones and Caitlin on the dance floor during the epic performance.
