Garth Brooks was so moved by a fan who offered the country star his Special Olympics medals that he traded him his own guitar during a concert on Friday (09Jan15).

The Friends in Low Places hitmaker is currently in the middle of his sold-out comeback tour, and during the first of Brooks' hometown shows in Tulsa, Oklahoma, he spotted a man named Nathan Putman in the audience, who was holding up a photo of the two of them together.

According to local news site Tulsa World, the pair previously met in 2007, when Putman was competing in the Special Olympics while Brooks served as a volunteer.

When Brooks was handed the photo, he was in the middle of his track That Summer, and briefly stopped singing as he teared up upon viewing the special picture up close.

Putman then asked security to hand Brooks three of the medals he won from the competition for people with intellectual disabilities earlier this month (Jan15), and when the precious prizes reached Brooks, he promptly put them around his neck.

In return, he took off his guitar and passed it to Putman, who proudly held it up for the thousands of cheering fans in the arena.

The emotional moment comes months after Brooks shared a similar interaction with cancer-stricken fan Teresa Shaw in Minnesota. She held up a sign which read, "Chemo This Morning, Garth Tonight. Enjoy The Dance", and the country icon also gave her a guitar.
