Not THAT Little Drummer Boy, the other one! Couldn't seem to find the lyrics as sung by MacMurrough on this album so I thought I'd post them here for reference.

LITTLE DRUMMER BOY (as sung by MacMurrough on Merry & Fine (1977)

I was brought up right well me lads and when I was sixteen
I ran away from home me lads and a soldier I became
With a fine cap of feathers, likewise a rattling drum
They learned me to play upon the rub-a-dub-a-dum

(CHORUS)
With a fine cap of feathers, likewise a rattling drum
They learned me to play upon the rub-a-dub-a-dum
With a gentle waist so slender and fingers long and small
I could play upon the rub-a-dub the best of them all

And it's many years the pranks that I saw amongst the French
And boldly I did fight me boys although I'm but a wench
And in buttoning up me trousers, how often have I smiled
To think I lay with a thousand men and a maiden all the while

And they never found me secret out until this very hour
And they sent me up to London to be sentry at the tower
And a lady fell in love with me and I told her I was a maid
She went unto me officer and me secret she betrayed

He unbuttoned up my red tunic and he found that it was true
It's a shame, he said, to lose a pretty drummer boy like you
So now I must return to me family at home
And along with my bold comrades no longer can I roam
