I just googled the first line of this song and found this fantastic thread. I remember my younger brother singing it (he learnt it at playschool back in the 70s). I just couldn't remember the two lines before the blowing a kiss bit but this thread has jogged my memory.

Here's what my brother used to sing:

I'll telephone and tell a Mr Santa Claus
I hope he will call tonight.
Down the chimney he'll come creeping
Im my bed I will be sleeping
Hang up all your stockings on the fire place
And blow out the candle light
Jump into bed, cover up your head
Blow a kiss - goodnight.

I can't wait to sing the whole thing to my three year old daughter!
