A couple of tuneful carpenters got into the Christmas spirit last week, recording and uploading their rendition of Mary Did You Know?  The video’s gone viral, garnering well over 30 million views since December 2.

“The Singing Contractors” — as Aaron Gray and Josh Arnett call themselves — have been duetting at construction sites and posting the results since 2012. What started as a lark became a sensation in September of 2015 when they released a performance of How Great Thou Art, which has now generated over 15 million Facebook views. 

Devout Christians, Gray and Arnett say they make videos to spread the “message of hope in song.” The duo told Fox News that their musical efforts have inspired and changed lives in amazing ways. “We have received so many messages of encouragement and some situations saved some from suicide. It’s been totally overwhelming and we are so humbled to be used for this … that God would use a [couple] of old guys like us.”

Let’s enjoy a few holiday favorites from these harmonizing handymen, along with the classic Christian hymn that first put them on the ladder of musical success.
