We quite understand we'll whisper the band
What never must be repeated,
That every penny no matter how many
Is paid and bill receipted:
And never a word of what has occurred
We'll drop to any chum,
We swear! we swear! that everywhere
We'll be mum! mum! mum!
We'll be mum! mum! mum!
Be mum! be mum! be mum! be mum!

Be mum! be mum! be mum!

We quite understand and we'll whisper the band
That now every penny no matter how many is paid.
Mum! mum! mum! mum!

Should anyone go like this (all nudge one another) "I know" -
We'll hope that no one goes so -
You ought to reply with t'other eye (all wink)
And finger to nose so! (They suit action to word.)
Or make the sign of the classic line,
"He spoke no word of doubt,
We'll be mum! mum! mum!
Be mum! be mum! be mum! be mum!

Be mum! be mum! be mum!

Should any be going like this! tho' we hope its not done
You must quickly reply with the opposite eye!
Mum! mum! mum! mum!
Should any be going like this!
You must quickly reply with the other and opposite eye!
