Since my wife is disabled, she's not able to make it out for Advent. We sing this together every morning instead.
The video was shot in "night mode" which means fewer frames per second. I intentionally framed it so we really weren't in the shot much, but our precocious papillon didn't always oblige, *grin*
About what we're signing, from the Wiki:
O come, O come, Emmanuel is a translation of the Christian Latin text ("Veni, veni, Emmanuel") by John Mason Neale in the mid-19th century. It is a metrical version of a collation of various Advent Antiphons (the acrostic O Antiphons), which now serves as a popular Advent and Christmas hymn [ca 8th - 12 centuries] the text is based on ... Isaiah 7:14 that states that God will give Israel a sign that will be called Immanuel (Lit.: God with us). Matthew 1:23 states fulfillment of this prophecy in the birth of Jesus of Nazareth.
