Legendary mother-daughter duo the Judds opened the ACM 'Superstar Women of Country' special with their 1985 single, 'Girls Night Out,' appropriately.

Wynonna and Naomi chose a fitting song -- their third hit to make the country music charts -- to introduce Reba McEntire, Martina McBride, Carrie Underwood, Jennifer Nettles and Miranda Lambert to the stage for the start of the girls-only event.

The Judds, who have been going strong as a country music staple since the early '80s, were honored during the CBS special for having won Vocal Duo of the Year seven years in a row. In addition to their ACM awards, the pair also holds nine CMA trophies and five Grammys for Best Country Performance by a Duo or Group with Vocal.

The one-night-only 'ACM Girl's Night Out: Superstar Women of Country' show was taped on April 4, following the ACM awards in Las Vegas, but aired for the first time on April 22.
