Happy Birthday To You's complex, sordid copyright history

Fred sez, "Prof. Robert Brauneis of GW Law School has done a mind-boggling amount of research into the origins and copyright history of 'Happy Birthday to You,' a song that still makes $2m per year for its copyright owner. Not only does Prof. Brauneis debunk many old myths about the song, he also concludes that the song is almost certainly in the public domain, although it's probably too expensive for anyone to actually prove that in court. But Prof. Brauneis is posting more than 200 documents unearthed in his research, so you all now have a head start."


(Thanks, Fred!)
