Aaron Rodgers‘ contributions to the state of Wisconsin extend far beyond the confines of Lambeau Field.

The Packers quarterback’s “It’s Aaron” Web series, which involves Rodgers paying surprise visits to those whose lives have been affected by Wisconsin’s various nonprofit organizations, is currently in its second season. The project most recently allowed Rodgers to meet Kelly, a 13-year-old Packers fan suffering from spina bifida.

Kelly loves to sing, and Rodgers isn’t too shabby on the guitar, so the two got together to record a few tunes onstage at Milwaukee’s historic Pabst Theater.

Check out their duet in the video below.
