Maybe the copyright laws are different in Europe than in USA?
From Wikipedia the copyrights in Europe:
"The rights of authors are protected within their lifetime and for 70 years after their death; this includes the resale rights of artists."
"The rights of performers last for 50 years from the distribution or communication of the performance, or for 50 years from the performance itself if it had never been communicated to the public during this period. The rights of phonogram producers last for 50 years after publication of the phonogram, or for 50 years after its communication to the public if it had never been published during that period, or for 50 years after its creation if it had never been communicated to the public."
