Per https://lemmy.world/post/13320356, they got a takedown notice and started going through everything with a fine toothed comb.
“John Larkin” by John Larkin only has two copies in existence, one by his widow and the other by an unknown person. If that name seems unfamiliar, it’s because he later became more famous as Scatman John.
It was recorded in 1986 but due to current US copyright law, it won’t enter public domain until December 3, 2069.
There’s a few copies floating around on YouTube and a FLAC version as a torrent. Pirates are keeping his legacy as a jazz performer alive.
Their legal page mentions the Netherlands, Finland, and Germany. I don’t know which of the latter two they’re hosted in but their hosting company is German, and Germany are a bunch of assholes when it comes to copyright.
