Well, the single was issued by The Springfields in 1961 on the Philips label; it was the A side of the single, issued in November 1961 and made 16 in the UK. What - if anything - it did elswhere, I don't know. I'm not a record collector, so I couldn't say whether or not the single is rare.
You may be able to find an original single on Ebay; possibly you can find a copy of the LP The Springfields Story - that's the LP where our library track originated.
It's on YouTube, and I've posted the link below; just high light it, copy it into your address bar and press GO. It'll take you straight to the link on YouTube and start playing it; I've tested it.
If your computer is less than ten years old, it should have the facility to play MP3 files. If nothing else, you could always download an older/smaller version of Winamp from the Winamp site.
More than this I can't suggest, but you're still welcome to a copy of the track if you want one.
