After launching the most successful country-music tour to date in 2006 and ’07, Tim McGraw and Faith Hill are doing an encore as a sort of extended 20th-anniversary present to themselves — and their fans, of course. Appropriately enough, the couple fell in love when Hill was opening act on McGraw’s Spontaneous Combustion tour in 1996; since then, they’ve each climbed to the uppermost rungs of Nashville’s A list and raised three girls together. (Hill has not toured since 2007.) Houston is a late stop on this 65-date tour, a four-part program that sandwiches solo sets by each performer between the big-time duets — “I Need You,” “It’s Your Love,” new single “Speak to a Girl” — that made them country’s biggest first-name-only couple since George and Tammy, only with a much happier ending.
