It's not hard to see why this video went viral over Memorial Day weekend. 

It features a man singing God Bless America at a Wilmington, North Carolina, Walmart on Saturday. 

The man, dressed in an American flag t-shirt, belted out the patriotic song a capella near the checkout lines, drawing a big round of applause from the delighted shoppers.

Commenters pointed out that they've seen the same man singing in other area stores around the holidays. Another person posted a video of the man singing in a Golden Corral.

The video, posted by Barbie Clancy on Facebook, has now been watched nearly half-a-million times.

Her son let her know at one point that the video was going viral... 

"Mom your video is about to go viral #Viral," Michael Clancy wrote. 

"What does that mean?" she answered.

"It's going to a lot of people," he responded.
