Kacey Musgraves raised more than a few eyebrows with her 2013 single "Follow Your Arrow," which says, in part, "Make lots of noise / Kiss lots of boys / Or kiss lots of girls if that's something you're into." But during her performance as part of NPR's Tiny Desk Concert series -- which happened to fall on the same day as the legalization of same-sex marriage throughout the United States -- Musgraves sang the tune in celebration.

"How great of a day is today?" Musgraves asked during her performance. "It really is crazy, and if I keep talking about it, I'm going to get emotional. My sister called me this morning, ugly-crying about the legalization of gay marriage. I just think it's insane. And so while we're here, I would love to do "Follow Your Arrow." I think it's appropriate.

"Now that it's all legal, I don't have anything to sing about," she added jokingly.

Musgraves also tweeted about the historic ruling, saying, "PROUD to be alive on this historically fabulous day."

The Texas native acknowledges that she almost didn't include "Follow Your Arrow," which she wrote with Brandy Clark and Shane McAnally, on her freshman album, Same Trailer Different Park, fearing the repercussions.

“At first, I was like, ‘There’s going to be backlash,’” Musgraves tells The Boot. “I know a lot of people don’t really agree with those things, especially in the South. But there’s actually a lot less criticism towards that song than I imagined. I’ll play it at shows where there’s a huge age range of people, and even the older people are getting into it.

"More than anything, even if they don’t agree with the girls kissing girls thing or even the drug reference, I would hope that they would agree that no matter what, we all should be able to love who we want to love and live how we want to live," she continues.
