Meet 4-year-old Riley.  Riley has Asperger's Syndrome and is probably Luke Bryan's biggest fan.  His mom says that Luke's music inspires Riley and makes him so happy.

Well, the radio station, WGNA, got in touch with Luke and together they gave Riley and his mom the surprise of their lives.

Just a warning...this will probably make you cry a little.  It's amazing, though.  Great job, WGNA.
