A local delivery driver is bringing joy to his customers with holiday cheer and music.

Brett Batts works for UPS and is becoming known as “Mr. Christmas” for singing to package recipients in Naperville.

“When they allow me to, I will definitely do it,” Batts said. “I’m always moving. So when I see that little window open, I seize the moment.”

A video of Batts singing a Christmas song to customers inside a clothing store in Naperville recently went viral on social media.
