The Automatic singer brought her Roadside Bars and Pink Guitars tour to Augusta and invited two special guests on stage with her, Ashley Monroe and Angaleena Presley.

In fan-shot videos and photos posted on social media, the ladies seamlessly reunited to sing their hit Hell on Heels, and showed off their line-dancing skills for the audience.

The group last released an album in 2013, and they were slated to hit the road on a subsequent tour. However, all tour stops were cancelled in June, 2013, due to "unforeseen circumstances".

Lambert's other surprise came when she invited country singer Patty Loveless to join her for a duet, and at the end of the show, all the special guests were brought back to the stage to join Lambert for the finale.
