Arista Nashville/McGraw Music/Sony Music EntertainmentFor Tim McGraw and Faith Hill, the day that was more than twenty years in the making has finally come. Today, the couple releases their very first full album of duets together, titled The Rest of Our Life. At the same time, the two get the chance to look back on a year of touring together, as their Soul2Soul concert special premieres at 9 p.m. ET tonight on Showtime. For Faith, there’s no denying it: it’s been a wild ride.
