Dan Smyers and Shay Mooney of Dan + Shay took over the outdoor stage at Jimmy Kimmel Live in Hollywood on July 31.

In addition to performing their recent No. 1 hit, “Tequila,” the duo treated fans to a rendition of their upcoming single, “Speechless,” which will ship to country radio on Aug. 6.

Penned by Dan Smyers, Shay Mooney, Jordan Reynolds and Laura Veltz, “Speechless” was inspired by Dan’s marriage to Abby Law (May 2017) and Shay’s marriage to Hannah Billingsley (October 2017). The video for “Speechless” features footage from both Dan and Shay’s weddings.

“Speechless is definitely inspired by our wives,” says Shay. “It’s very cool to release songs that are not only stories of our lives but also very personal experiences. Seeing our wives for the first time in their wedding dresses was absolutely an unforgettable and we talked about that while writing the song and bringing that moment to life in this song.”
