Just noticed this at the bottom the the above listing, I'm pretty sure that the seller is contravening one of these? How long copyright in sound recordings lasts
The length of term of copyright in a sound recording depends on whether or not it has been published (released) or has been communicated to the public (for example, played on the radio)
if a recording is not published or communicated to the public, copyright lasts for 50 years from when the recording was made
if a recording is published within 50 years of when it was made, copyright lasts for 70 years from the year it was first published
if a recording is not published within 50 years of when it was made, but it is communicated to the public, copyright lasts for 70 years from the year it was first communicated to the public
if a recording is first communicated to the public within 50 years of when it was made and is then published at a later date (but within 70 years of its first communication to the public), copyright lasts for 70 years from the year it was first published
