Hello
To come back to the information provided by the SACEM catalog of works
When, after searching for a title, you get back only the name of the composer, the arranger, the author, but nothing more, it can mean two things.
The first - in the absence of a publisher's address - is that nothing has been printed, edited, distributed by a professional.
Second, it is possible that a self-publishing exists. But in this case, only the rights holders can distribute it.
If the only rightful owner is still of this world...see directly with him...otherwise...his heirs.
