You can see the label online, it apparently sold on eBay back in 2013 for £1.18 (or 99p?). The records you’re looking for are probably like many I’m interested in - rare, but not valuable as such.

You say you’ve never heard the song, but are you not familiar with it at all? It was from the musical Carousel, and quite well known.
