Mcgraw's Birthday Present To Young Fan

Luke Wood was treated to the concert in Oklahoma City, Oklahoma as a birthday treat from his mother Kendra.

But the young fan was shocked when MCGraw invited him onstage.

Kendra tells People.com, "My son Luke has been a fan since he was three-years-old and always has said that he was going to sing with Tim MCGraw someday.

"He made a simple sign, 'Can I sing with you?' And brought it with us. I was completely shocked when Tim started singing 'Last Dollar (Fly Away)' and motioned for him to come forward. Before I knew it he was whisked onstage, Tim handed him a mic and began singing with Luke."

Kendra - who videoed her son and his hero on her cell phone - adds, "I have no idea how I am going to top this birthday present!"
