See what it looks like when a full orchestra and a huge choir perform "O Holy Night" during a flash mob at the "Museum of Fine Arts" in Boston here:

O holy night
The stars are brightly shining
It is the night of our dear Savior’s birth
Long lay the world in sin and error pining
Till he appeared and the soul felt it’s worth

The thrill of hope, the weary world rejoices
For yonder brinks a new and glorious morn
Fall on your knees

O hear the angel voices
O night divine
O night when Christ was born
O night divine
O night, O night divine

O Holy Night
The stars are brightly shining
It is the night of our dear Savior’s birth
Long lay the world in sin and error-pining
Till he appeared and the soul felt it’s worth

The thrill of hope, the weary world rejoices
For yonder brinks a new and glorious morn
Fall on your knees

O hear the angel voices
O night divine
O night when Christ was born
O night divine
O night, O night divine

(Text: John Sullivan Dwight, melody "Cantique de Noël": Alphonse Adam)
