Wow, those are indeed fun facts! So much I didn’t know, like the fact that there’s a word for the type of movie sound track that can’t be heard by the characters in the film.

I have things like that movie you can’t remember except for the song that have been stuck in my head for many years, and which I’ve never thought of at all until something triggers the memory. I can certainly recite many commercial jingles from the 60’s and 70’s!
