Underwood surprised John and Cara Martin and their two girls before the concert, also giving them a free trip on a cruise in the fall where she’ll perform in a private concert for 1,000 military members courtesy of Carnival and Operation Homefront.

“I’ve been able to sing songs like ‘See You Again,’ where people are like ‘man, my husband just left’ or just came back or whatever, and that song means a lot.” Underwood said.

John has done three tours of duty overseas and after ten years, the couple still has not taken their honeymoon yet.

“It brings tears to my eyes,” Cara said.
