Eloise at Christmastime by Kay Thompson

Yes
Here she is at Christmastime
Complete with tinsel and holly
Singing fa la la la lolly
And over the roar of the jingle bells
You can hear hear hear her say
It's absolutely Christmas
But I don't mind a bit
I give everyone a present
For that's the thing of it
So when it's everly Christmastime
And you're under your Christmas trees
Simply tinkle a bell and have a trinkle
And remember
Me
Eloise
