O, Christmas Tree
There are various English-language versions of "O, Christmas Tree," each of which traces its origins to a traditional German folk song that, at least initially, was unrelated to Christmas. That changed over time, and by the mid-19th century the song was being sung as a Christmas carol.
"O, Christmas Tree"
O Christmas Tree O, Christmas Tree,
Your branches green delight us.
O Christmas Tree, O Christmas Tree,
Your branches green delight us.
They're green when summer days are bright;
They're green when winter snow is white.
O, Christmas Tree, O, Christmas Tree,
Your branches green delight us!
O Christmas Tree, O Christmas Tree,
You give us so much pleasure!
O Christmas Tree, O Christmas Tree,
You give us so much pleasure!
How oft at Christmas tide the sight,
O green fir tree, gives us delight!
O Christmas Tree, O Christmas Tree,
You give us so much pleasure!
O Christmas Tree, O Christmas Tree,
Your branches green delight us.
O Christmas Tree, O Christmas Tree,
Your branches green delight us.
They're green when summer days are bright;
They're green when winter snow is white.
O Christmas Tree, O Christmas Tree,
Your branches green delight us!
