Don't bother to ask Trisha Yearwood when she and Garth Brooks will tie the knot.

"I know I'm going to get asked about it in every interview," the country star said before she was even asked about it. He popped the question in May. "I haven't set a wedding date and if I had, I wouldn't tell anybody what it was."

What she will divulge is that her new Top 20 single, "Georgia Rain," with her man on harmony vocals, was rewritten slightly at her request.

"I asked [the songwriters] to make it a little more personal for me," said Yearwood, a Georgia native who sings Thursday at Mystic Lake Casino.

In other words, she asked to change the line "A gust of rain on red Georgia clay" to "the Georgia rain on the Jasper County clay," reflecting where she grew up. Established singers can do those sorts of things with hungry songwriters.

"Jasper County" is the title of Yearwood's first album in four years. It debuted last month at No. 1 on Billboard's country chart, selling 117,000 copies in its first week, placing it No. 4 on the pop list.
