Two singing Indiana contractors hope their newest duet will be their biggest hit yet.
Aaron Gray and Josh Arnett say they liked the message behind the popular song "Mary Did You Know."
They decided to record it in a garage last week after only singing it together once.
Their last duet has 15 million Facebook views.
They think this new one will be their most watched video yet.
Aaron Gray, singing contractor said, "We had one video go viral, it was How Great Thou
Art, and then here about a year later, we've had this other video go viral, and it's just been crazy ever since."
Arnett and Gray have had the opportunity to sing at both the Indiana state house and the governor's mansion over the past year.
