Surprise cameo appearances from rockstars are cool, but the most memorable onstage moments usually involve the least likely fans. Luke Bryan makes a habit of bringing kids on stage, but moments involving Kenny Chesney and Toby Keith also make the list of nominees in the Most Unforgettable Onstage Surprise category at the 2015 Taste of Country Fan Choice Awards.

You can watch all the videos below.

Keith brought a 93-year-old war veteran out to help close his show and left everyone in tears. Even the singer couldn't hold himself together when Lt. Colonel Harry Frizzell Sr. says "God bless America."

Chesney gave one lucky fan a special kiss — how could he say no? She practically dared him to do it!  — and Tim McGraw brought out an 18-year-old beauty with a beautiful voice ... his daughter!

Choose one of these, or Bryan's experience with a fan in Sioux Falls, or one of Miranda Lambert's moments from the  past year. Parmalee's power outage is also included. You can vote up to once every hour until this poll closes on Nov. 30 at 11:59PM ET. The 2015 Taste of Country Fan Choice Awards are 100 percent decided by fans.
