WOW. This is something straight out of ABC's Nashville. You may remember a song titled Travelin' Soldier, it was written in the mid '90s by Texas singer/songwriter Bruce Robison. The song was later covered by the Dixie Chicks, and included on their 2002 album Home. In fact, it became the Texas trio's last No. 1 single, back in 2003.

Well, recently 12-year-old Audrey McGraw, daughter of Tim and Faith, sang the song before her fathers concert in Dallas and just, WOW.

Listen to Natalie Maines of the Dixie Chicks singing with Robison and his wife Kelly Willis, below.
