Tim McGraw [ tickets ] and Faith Hill [ tickets ] have once again extended their successful Soul 2 Soul tour, according to the tour’s official website. The husband and wife duo--who began the jaunt as a summer outing last July--now have U.S. dates scheduled until Dec. 2.

The duo's current tour features complete sets by each artist, as well as several duets by the married couple throughout the night.

Their tour has grossed an average of $753,630 per city, and has played before an average of about 15,700 fans per city, according to Pollstar.
