Query: Old music on a newer medium

I've loved this song since I was a little kid and just had to have a copy of my very own. There seems to be a number of publishers who have this song for sale but I doubt any one version is any better than another. It was recorded late 30s or early 40s so the sound quality is what it was then. As I understand it the music is based on an opera tune. It's worth a listen.
