I've only ever seen it on cassette. You might be able to get in touch with Mr. Bee or his son Barry Cormier to see if they have any extra copies of it still.
You can get a chord from radio shack that goes from the radio (red/white tips) to head phone jack on your computer and download a program called cake walk. You'll be able to turn your cassette into mp3. You can separate the tracks too
Hi my dad is one of the musicians on that record and there were cd's that were produced. We had some extras at one time I can check to see if we still have some. If you want to email me at troylejeune@hotmail.com we can get in touch and I can check for you.
