I wonder if anyone can provide the words for this song, which I learned as a child in England in the 1950's (from the BBC schools programme "Singing Together")?
This is all I can remember of the words:

My grandsire beat the drum complete
His name was Darby Kelly O
No man so true at rat-tat-too
At roll-call or reveillez O

When Marlborough's name first rose to fame
So loud he rolled the points of war
At Blenheim he and Ramillies
Fired all their cannons to the core

With row-dow-dow
With what a shout the boys came out
The girls they waved, you don't know how!

And now (small shame) I bear the name
And drum of Darby Kelly O
No man so true at rat-tat-too
At roll-call or reveillez O

I've not been able to find any reference to it.
