STAGE TUBE: Jonathan Groff Performs Holiday Classics with Pennsylvania Students

Broadway vet and FROZEN star Jonathan Groff recently stopped by Conestoga Valley School - his former elementary school - to sing a number of holiday classics with the students. Check out the group's performance below!

Groff was reportedly asked by his mother, a physical education teacher at the school, to attend Conestoga Valley's annual sing-a-long.

Besides SPRING AWAKENING and GLEE, Groff also appeared in the Shakespeare in the Park productions of HAIR and THE BACCHAE, the off-Broadway plays THE SINGING FOREST and A PRAYER FOR MY ENEMY, Ang Lee's TAKING WOODSTOCK, and most recently, in the Starz series BOSS, alongside Kelsey Grammer.
