Welcome home vinyl restoration

Ok so, in the merchandise page there is this horribly damaged vinyl that plays in a video, and I thought there was probably something behind it and so i tried restoring it and i got to this point.

My guess to what this says is:

<unkown person, perhaps Alex> :"Someone's there [humming in tune] on a summer's day!"

[moment of pause]

<unkown person 2> :"Alex (?) numbers (?) are falling DOWN, DOWN, DOWN!"

<sounds like Julie here> :"Oh jeez! I'm gonna fetch the tomatoes" [kinda out of place but that's what it sounds and we know Frank and Julie were growing tomatoes in the yard, so something with that?]

If we follow the numbers given on the page these vinyls are from 1970 to 1972, and we are assuming by what is said in the main page welcome home was pulled from television in 1974, so perhaps the "numbers are falling down" is referring to the show loosing viewers?

This is the original audio i managed to get, inc ase you wanna try your hand at recovering it too.

Sorry if both these audios are kinda weird I did them in VLC media player.

Another interesting thing about this audio is the spectrogram, which has some weird artifacts

Now some of these are normal, for example:

^ This bands are where the character's voices are, and all the different stripes one over the other are the notes at which they talk or sing at and their resonant frequencies.

This on the other hand is the part between 20khz and 5khz, which is mainly static and a weird non repeating humming. This makes me think that these weird signs actually mean something, maybe morse, or maybe something else completely.

I invite you to try download the audio and look at the spectrogram yourself, to try and see what you get.

Also tell me what you hear in the restored audio! who know maybe you have better ideas than mine.

Until next time, don't forget to wave up high!
