[TOMT] [SONG] [80's or older] ethereal theremin-sounding jingle

This tune popped into my head a couple days ago and cannot figure out what its called or where specifically l've heard it. To my best memory, it sounds like it's done on a theremin, and I think it's sometimes played in older cartoons when something spooky/ethereal happens. It could also be a really weird guitar like in the song Sleepwalk, but I'm leaning towards a theremin. It sounds like it's being sung by a ghost.

The link is to what I remember the tune sounding like but on piano. It's not allowing me to officially add it as a link tho :[
