What is this and why did Capitol Records put it out?

Wouldn't It Be Nice (Cavalry Remix):

Originally thought this was an unauthorized fan remix, but the YouTube description indicates this was put out by Capitol Records. What is this mess?

What the hell?   

No idea what that's all about, but yes it's bizarre that it's on the BBs' official channel. I do notice that it's dated 2018 on various streaming services.  Maybe a remix for a movie or TV show featuring a cavalry scene?  It'd be a bizarre-as-hell music choice for a cavalry scene, but it's a bizarre-as-hell remix so who knows...

Interesting mix... I'd say it's a good bet this was created for a film... possibly a Vietnam War-era production... possibly a flashback sequence where a soldier is thinking of his girl while in the middle of a  combat sequence.

Great find! Their most recent post is this ad for Apple TV+ which features the remix: https://www.youtube.com/watch?v=M1fI8BL7BnE

So mystery solved! A commission for an ad. Still weird Capitol put it out as a single…
