O Christmas tree

It's almost, but not quite, too late for this:

O Christmas tree, O Christmas tree,
O Christmas tree, O Christmas tree,
O Christmas tree, O Christmas tree,
O Christmas tree, O Christmas tree,
O Christmas tree, O Christmas tree,
O Christmas tree, O Christmas tree,
O Christmas tree, O Christmas tree,
O Christmas tree, O Christmas tree!

Sung to the tune of 'O Christmas tree'.

O Christmas Tree

O Christmas Tree, O Christmas Tree,
O Christmas Tree, O Christmas Tree!
O Christmas Tree, O Christmas Tree,
O Christmas Tree, O Christmas Tree!

O Christmas Tree, O Christmas Tree,
O Christmas Tree, O Christmas Tree!

O Christmas Tree, O Christmas Tree,
O Christmas Tree, O Christmas Tree!

-to the tune O Christmas Tree.
