That's not to say these two don't know how to party! "Everybody was on the dance floor all night," Brandon said. "The way the wedding ended, everyone was still on the dance floor. We played John Denver's "Take Me Home, Country Roads" and everyone got in a huge circle and was swaying."
Earlier in the night, the newlyweds shared their first dance to "Let It Be Me" by Ray LaMontagne and the bride sweetly danced with her father to Tim McGraw's "My Little Girl."
But when it came to LANCO's breakout hit single, "Greatest Love Story," the couple had no plans to play it.
"I played it for Tiffany on an acoustic guitar years ago. That was our moment with the song," Lancaster said, admitting that he wasn't surprised that one of their pals ended up putting in a request for the song with their DJ.
That song -- which is currently sitting pretty in the iTunes Top 10 -- has already served as the backdrop for countless proposals this summer, with numerous fans popping the question during LANCO's live performances.
"As a songwriter, as a musician, you always dream of your songs being a part of people's lives," Brandon said. "Music is kinda the soundtrack to our life -- happy times and sad times, maybe a Friday night anthem -- but this one is cool because not only are you now the soundtrack to someone's life, but you're part of their story that they're gonna have forever. It's been a really special thing."
