How can I get a clear/good quality version of an oldish song?

[FknOmniShambles]

Probably a silly question but I'm trying to get a good quality version of a song from the 1950s - it's called Forgotten Dreams by Leroy Anderson and it's the piece of music I'm hoping to walk down down the aisle to, and it's a gorgeous tune. (it's known the Cat Song in our house as when you whistle it to the cats they go mad!)
YouTube and Spotify have versions but they're scratchy... Does anyone know of any way I can find a clear quality version of this?
Any help gratefully appreciated!

That’s just fabulous, thank you.

that sounds good and not scratchy

Or its on Amazon Music in good quality

iTunes has it, 79p.

Thanks! I thought the YouTube one was a bit scratchy but I may be being picky. Will take a look at the amazon/iTunes versions now. Despite knowing nothing much of the song itself or the composer, it's a really special piece of music for us and one of the other is us are often whistling it to get the cats' attention! It's our way of including them in the day...
