Urs: 
O holy night! The stars are brightly shining, 
It is the night of the dear Saviour's birth. 

David: 
Long lay the world in sin and error pining. 
Till He appeared and the soul felt its worth. 

Carlos: 
A thrill of hope, the weary soul rejoices, 
For yonder breaks a new and glorious morn. 

Sébastien: 
Fall on your knees! Oh, hear the angel voices! 
O night divine, oh night when Christ was born; 

Urs: 
O night divine, oh night oh night divine. 

O holy night! The stars are brightly shining, 
It is the night of the dear Saviour's birth. 

Carlos: 
Sweet hymns of joy in grateful chorus raise we, 

Sébastien: 
Let all within us praise His holy name. 

Christ is the Lord, 
Let everyone in grateful chorus raise we (not sure about this part) 
O night, o night 
O night, o night divine 
O night, divine, o night 
O holy night.
