The song has become a staple during timeouts at sporting events, with the stadium camera focusing on fans who are expected to smooch, sometimes with comical results.
"I heard about that," Nash told The Associated Press. "That's awesome. It kind of makes sense, and it was such a big song. I thought it was cute. I'm glad they have a song that was appropriate."
Nash performed a brief acoustic set at the JPMorgan Chase Open women's tennis tournament Friday night, singing "Kiss Me" and new songs from her debut solo album "Blue on Blue," due out Tuesday.
"I've played almost every possible scenario — funerals, weddings, sports events, you name it," she said.
Sixpence dissolved in 2004, and Nash and her husband moved to Los Angeles, where she wrote several of the songs for the album and gave birth to her first child.
"It's about the song and the lyrics," she said. "In Sixpence, there was a lot going on and I felt like I was kind of drowned out all the time. I was having to fight to get over the instruments and the guitars."
Nash's album is on One Son Records, her label named for her 2½-year-old son Henry. She will tour this fall with Jars of Clay and Matt Wertz.
"If I wasn't as content and happy with the record as I am, I might feel a lot more freaked out," she said. "But I stand behind it and I feel really positive about it and the work that was put into it."
