This post is not history - this is now. I wish I knew a little more about Betty but maybe you can find out on her Blog. She is Canadian Chinese living in Chapala and seems to be having a good time of it with her family. Here's a video of her son singing a simple English/Spanish lesson.
Here are the lyrics in case you want to sing along.
Pollito Chicken,
Gallina Hen,
Ventana Window,
Puerta Door,
Mesa Table,
Silla Chair,
Lapiz Pencil,
Pluma Pen
And here's her Blog
