Music education runs in the family.

That's just one revelation Josh Groban made during his episode of the TLC show Who Do You Think You Are?, which takes a celebrity through their family's roots and history. In the below clip, Groban learns that one of his family members taught music, a fortuitous and emotional revelation for him.

"He would have had this book in his hands teaching his students?" Groban said when presented with an old music book. "To have a book like this is my own hands is extraordinary."
