I used to teach this song to my Primary School students! My name is Wendy so they thought it was a great song! I can't rememebr all the words but I know at the end she didnt' like being the fairyon that Christmas tree 'cos she "couldn't even clamber down to get a cup of tea!"

I had the sheet music to it too but can't find it now. I know where I got that music and I'd say it was about 1984-ish.

The title was 'Litte Wendy Wombat'
