Speechless: it’s both the title of Day + Shay‘s new song and the way they felt seeing their wives Abby and Hannah come down the aisle on their wedding day.

The country music duo composed of Dan Smyers, 30, and Shay Mooney, 26, released their latest love ballad, which is inspired by “the biggest moment” in their lives.

“I had this title ‘Speechless’ in my phone — you’re at the altar waiting for your bride to walk down the aisle, then that moment happens and you have nothing to say,” Dan tells PEOPLE. “I remember being up there on our wedding day – May 13, just a little over a year ago – and she walked up and I was at a loss for words.”

Dan and Abby married on May 13, 2017 in Tennessee, while Shay and Hannah tied the knot a few months later on Oct. 20, 2017 in Arkansas. And not only do they stand together on stage in front of thousands of fans, but they also stood by each other’s sides at their respective weddings.

“Shay had just gotten married also, so we both had that feeling fresh on our minds and we wrote about it,” Dan says. “Shay and I were both in each other’s weddings as groomsmen, and there were some fun moments in there of us tying each other’s ties.”

“It’s about not being able to find the words every single time, which is a special thing,” he adds. “When it came time to do the video and given the fact that we had both had weddings the year before, I was like, ‘Man, maybe this video is already done.’ I had the crazy idea of taking Shay and my wedding footage [and] parallel those stories to showcase the moments.”
