I can sing up I can sing down
Gradually ascend then, do it once again then
Do it very loud then do it very quietly
I would not want to scare you, it would be unfair to
Sing this song at Christmas time and scare you out of your wits

When he’s looking sad sing it to your Dad
And maybe to your brother then try it on your mother
It’s such a lovely thing that people like to sing
I stand around the piano with my good friend Ritchie Benaud
And even the Prime Minister occasionally drops in

I like to sing like this (like this) I like to sing like this (like this)
Do it with fortissimo then with pianissimo
You can have the choice so select a silly voice

(Silly voices)

Give yourself some headroom practice in the bedroom
And sing this song while standing on your head in the shed

Sing a silly song sing a silly song
Sing a silly song sing a silly song
Sing a silly sing a silly sing a silly (pause) - if you
Sing a silly Christmas song you can’t go wrong

(Silly voices)
