Robin bring your flute
Willie bring your little drum and come
Come be merry while you play
We'll be joyous as you play
On a Merry Christmas day!
When the men of olden days
Gave the King of Kings their praise
They had pipes on which to play
They had drums on which to play
Full of joy on Christmas Day.
God and man this day become
Join us one with flute and drum
Let the happy tune play on
Flute and drum together play
As they sing on Christmas day.
