Can you identify this ancient production music track?

Can you identify the bossa nova production music track that starts at 9:26?

Drive-in Intermission 6

Ideally, I'd like to find out where this recording came from and who wrote it.

Thanks!

As a kid, I went to a Christian summer camp in far northern California, and at lights out they played this terrifying hymn - it was a choir-based thing, maybe with strings. All I remember is that at one point it said "blessed God, ooh-ooooooh-oooh," and the record was banged-up/maybe played at the wrong speed, which made it sound like a lost artifact of the Civil War. For years I've wanted to find it so I can scare myself and have a backing track for my guitar noodling.

I feel like whatever insight helps you find this ancient ephemera will help me find mine.

That said, what do you wanna bet there's one defunct studio in Burbank that produced 99% of all such stock music between 1930 and 1960 and all the tapes and credits are wasting away in a Palmdale storage unit or a 95 year old man's attic?

the best sound library discography, imo, is here --

it is organized by label though so it might be too time-consuming a process to wade thru it all. maybe you can narrow it down with discogs.
