Solution by John Michael.


Xmas is over
The tree is down
He gave his life
Our evergreen so proud
Triumph of life over death
Christmas is over
Until next December
The sun god of winter
Protects light until summer
And the tree will grow
Waiting for ornaments, love, And lights to glow
And to twinkle again
