At the Friday night stop of Miranda Lambert and Dierks Bentley's Locked & Loaded Tour there was quite a surprise in store for the fans of Dayton, Ohio. 

A special guest decided he would pop on stage with a guitar and play a little tune. Who was it? None other than Mr. Miranda Lambert, aka, Blake Shelton.

Yeah, Blake decided the packed house needed to hear HIS new single instead of Miranda's. (Not really, but it sounds gossipy.)

So, enjoy Miranda and Blake and their live, acoustic version of "Sure Be Cool If You Did."
