Name of this song?

I was watching “When Star Wars Ruled the World” and at one point they use a song that sounds a lot like a song used in the western. It’s mostly whistling with a little guitar. It starts playing when they start talking about Han Solo being frozen. Has anyone heard this

Also, any name of any western song with whistling and guitar will be greatly appreciated.

Could be the theme from “The Good, The Bad and the Ugly” by Ennio Morricone. I think that’s the one with the whistling. Anyway, he’s the person to look to - he scored a lot of the old spaghetti westerns, and your description sounds a lot like his style.
