The couple is in the middle of Brooks' comeback world tour, and decided to make an unannounced stop in Nashville, Tennessee.

Fellow country music star Vince Gill introduced Yearwood to the stage and she then told the audience, "I didn't have a chance to bring my band or call them or anything, but luckily, I live with a Grand Ole Opry member, so if you all would make welcome my guitar player tonight, my husband, Mr. Garth Brooks!... We rehearsed in the truck on the way here..."

The duo sang Yearwood's first number one hit She's In Love With The Boy, before covering a number of country classics including I Don’t Want to Have to Marry You by Helen Cornelius and Jim Ed Brown, who died earlier this month (Jun15) after a battle with cancer.
