Hi Boab,

This is the number you are referring to :-

The day is ending little drummer boy,
Lights out was sounded long ago,
So close your eyes my little drummer boy,
And say goodnight to all your friends and foes.
Reveille will sound in the morning,
And once more on parade you will go,....

and there I'm afraid, my memory fails me for the last couplet.

I have searched for ever on the net to find it, to no avail. :(
