Country music star Tim McGraw, fresh off far bigger shows last week in St. Paul, performed for several hundred guests at a private fundraiser Sunday on Lake Minnetonka.

The acoustic show “Liberty on the Lake” benefited the nonprofit Folds of Honor, which provides scholarships to the spouses and children of U.S. service members killed or severely disabled in the line of duty.

Along with those who paid on dry land to hear McGraw, boaters on the lake behind the stage were allowed to take in the show for free outside the Palmer Pointe home of Snap Fitness founder Peter Taunton.

McGraw and his fellow country star wife, Faith Hill, performed Friday and Saturday at Xcel Energy Center.

The 50-year-old McGraw has joined forces with Chanhassen-based Snap Fitness to open a line of fitness centers that reflect his music and workouts. The gyms will be called Tru Mav Signature Clubs, a play on “true maverick,” and will be co-branded with Snap Fitness.
