Let's start with The Mr Ed Theme ....
At :33 you hear "this song is sang for the devil" (or something close)
... and at :38 it kind of sounds like "song for Satan"

I admit, I kind of hear it too ...
Odd, indeed ...
It was some religious nut that "found it, of course-of course ...

IRONTON, Ohio (AP) _ Church members singing ″Oh, How I Love Jesus″ burned record albums, cassettes, and other rock and country music paraphernalia after attending a seminar in which an evangelist said the ″Mr. Ed″ television theme conveys a satanic message to unwary listeners.

Jim Brown, an evangelist at Psalms 150 in South Point, said the Mr. Ed theme extols Satan when the record is played backwards.

″A Horse is a Horse,″ contains the backward messages ″the source is Satan″ and ″someone sung this song for Satan,″ Brown said during the seminar at the First Church of the Nazarene in Ironton.

About 75 teen-agers attended the record burning following the Tuesday night seminar.

I'll listen to it again and see if I pick more out ....

I'll try and find more songs like it ....

.... of course (of course), upon thinking, it makes sense that Mr Ed was Satan ....
How else could 1) a horse talk, and 2) a horse command a simpleton like Wilbur to do his every bidding?
