"We've been married, this'll be our 10th year, so I guess we've traveled on tour for 10 years," says McGraw, who kicks off the 71 Soul 2 Soul II tour with Hill Friday in Columbus, Ohio. "She's always been out with me -- and the kids -- when I've been working. It's just part of the program to us."
McGraw and Hill, who have three children, have toured together twice before. The first Soul 2 Soul tour was in 2000, and they were part of a George Strait stadium tour in 1996.
The Soul 2 Soul II shows will be staged in-the-round, and McGraw says the shows will be non-stop three-hour affairs with "seamless" transitions between his band, Hill's group and duet performances.
