This is a legal outcome that was long, long overdue and the copyright terrorists should be forced to issue refunds since they’ve been raking in $2 million/year for a rather ubiquitous tune.
It mostly took the efforts of a documentary film maker to finally get the ball rolling. The “publisher” wanted $1500 and this was the discounted rate. A judge listened to an expert who knew the song’s history (a pair of spinsters wrote in the 1890s) so the copyright technically ended in 1949 at the latest. Sure the sisters’ younger sibling filed it again in the Thirties but I agree with the judge, at best, it would only cover the arrangement, not the lyrics.
Next up, dragging that pharmaceutical shitbag through the streets by his heels.
