And, since the combination of Mary's Boy Child and O My Lord is so popular (not to mention being in the DT), here is that version:

Mary's Boy Child / Oh, My Lord

Mary's boy child, Jesus Christ, was born on Christmas Day

And we may live for evermore, because of Christmas Day.



Long time ago in Bethlehem, so the Holy Bible say,

Mary's boy child, Jesus Christ, was born on Christmas Day.



Hark! Now hear the angels sing, "A King was born today!"

And man will live for evermore, because of Christmas Day.

Mary's boy child, Jesus Christ, was born on Christmas Day.



While shepherds watch their flock by night, they see bright new shining star.

They hear a choir sing a song; the music seemed to come from afar.



Hark! Now hear the angels sing, "A King was born today!

And man will Live for evermore, because Of Christmas Day."

For a moment the world was aglow,
All the bells rang out, there were tears of joy and laughter.

People shouted, "Let Everyone Know 

There is hope for all to find peace."



Now Joseph and his wife, Mary, came to Bethlehem that night.

They found no place to bear her Child, not a single room was in sight,

And then they found a little nook, in a stable all forlorn,

And in a manger cold and dark, Mary's little boy was born.



Hark, now hear the angels sing, "A king was born today,

And man will live for evermore, because of Christmas Day.
"
Mary's boy child, Jesus Christ, was born on Christmas Day.



For a moment the world was aglow
All the bells rang out, there were tears of joy and laughter.

People shouted, "Let Everyone Know 

There is hope for all to find peace."

Oh, my Lord, you sent your Son to save us,

Oh, my Lord, Your very Self You gave Us;

Oh, my Lord, that sin may not enslave us,
And love may reign once more.



Oh, my Lord, when in the crib they found Him
,
Oh, my Lord, a golden halo 'round Him,

Oh, my Lord, they gathered all around Him,
To see Him and adore.



Oh, My Lord, with a just adoration,

Oh, My Lord, there came great jubilation.
Oh, My Lord, and full of admiration,
They realized what they had. (Until the sun falls from the sky!)

Oh, my Lord, (O praise the Lord!) they had begun to doubt You.
Oh, my Lord, (He is the truth forever!) what did they know about You?

Oh, my Lord, (O praise the Lord!) but they were lost without You,
They needed You so bad. (His light is shining on us all!)


Oh, my Lord, (O praise the Lord!) with a just adoration.

Oh, My Lord, (He is the new creation!) there came great jubilation.
Oh, my Lord, (O praise the Lord!) and full of admiration
They realized what they had (Until the sun falls from the sky!).

Oh, my Lord, (O praise the Lord!), You sent your Son to save us,
Oh, My Lord (This day will live forever!), Your very Self You gave us,
Oh, My Lord ... (fade out)
