I went to Catholic school for kindergarten, first grade, and second grade. Mrs. Groth was our music teacher, and I played recorder in her class and learned to sing. I mostly have good memories of her.
Only one memory stands out as a bad one. Around Halloween, she thought it would be a good idea to teach us this song:
Have you seen the ghost of John?
Long white bones with the skin all gone...
Wouldn't it be chilly with no skin on?
It was scary. I was afraid of skeletons and that tune (which was actually very catchy) would get caught in my head. I would expect to see a skeleton around every corner. Watching Jason and the Argonauts didn't help much either.
I think I went as a skeleton that year.
This is the best version of the song that I could find.
