What's the deal with the audio on the Studio Canal logo?

Is the sound designer a mad genius, or was this odd sound mix a "happy accident" as Bob Ross might have said?

Happy 4th from 1976

Here's the Sears summer catalog from our country's bicentennial year. How much patriotic red, white and blue type of stuff is in there? Not as much as you might think...

There's some red, white and blue polyester & cotton pants outfits.

The red, white and blue Chuck Taylor knockoff in the center of the page catches your eye, but it's those shoes on the bottom of the page that you need for the summer of '76...

It's 1776 Casual for Men and Big Boys.

If you quickly flipped by this page of "novelty print knit tops" you would have missed the biggest patriotic item in this catalog...

It's a George Washington tee shirt.

It's very possible this red, white and blue playground equipment was always manufactured in this color and has nothing to do with the bicentennial, but I'm gonna take what I can get. Also I'm wondering if those merry-go-rounds are still being sold. I never had one, but it seems like a product that could cause a great deal of injury.
