Harry Styles and James Corden demonstrate times when it’s absolutely not OK to sing

There are times when breaking into song is fun and playful and periods when it’s completely inappropriate.

In the video above, James Corden and Harry Styles show us some of those situations. For pattern, it’s not okay to break into song and dance while in the middle of an operating room or while destroying an explosive.

Save the singing for the stage, gentlemen. Lives are at post!
