Colton Swon of the Swon Brothers married his longtime love, Caroline Glaser, in a ceremony in Nashville on Saturday (March 17).

The couple tied the knot at the historic Houston Station, according to the Tennessean. Around 300 guests attended, including Carrie Underwood, with whom the Swon Brothers toured extensively.

Zach Swon served as best man during the brief ceremony, and was reportedly overcome with emotion when toasting his brother at dinner.

Glaser wore a bohemian-style gown with lacy short sleeves, and its long flowing skirt turned out to be convertible—made shorter for the reception. She wasn't the only one able to dance more comfortably: The couple passed out flip-flops for female guests to change into, in order to boogie the night away.

The younger of the Swon Brothers met Glaser, who is an indie rock singer-songwriter, in 2013 while both were competing on Season 4 of The Voice. The Swon Brothers finished third that year, which gave them the profile to launch their career.

Both of the newlyweds are busy with musical projects, so they'll defer their honeymoon for the time being.

The Swon Brothers Helped Out With This Surprise Proposal!

The couple announced their engagement on Feb. 25, 2017, and Swon went all-out planning the special moment. He assembled the couple's most memorable moments into a movie trailer and arranged to have a local theater run it between the usual trailers for upcoming movies. Swon invited both his and Glaser's families to accompany them to the movies, where he got down on one knee to propose after surprising his bride-to-be.

In addition to Underwood, Swon and Glaser invited several country stars that have served as mentors to the wedding, including Brad Paisley and Blake Shelton, who introduced them. They didn't have to hire a band for the wedding, Swon tells Taste of Country Nights.

"My friends would've killed me if I hired a wedding band and they weren't superb, because they're all great musicians," he said before the wedding. "So I'm leaving it up to them just to get up and jam and have a good time."

Musically, the Swon Brothers have just released an acoustic video for their new single "What Ever Happened."
