The bottom line is copyright can't be extended. The rightsholder can create a new workbased off the originalthat would have a new copyright, but the original creation's copyright expiration date would remain."
So, ctorres23: I'm assuming that if (for example) The Gershwin estate, were to only allow the Broadway production of "Porgy and Bess" from 2011 to be the only production available to license, they could keep receiving royalties until that copyright expires?"
Caveat: I'm not that familiar with the details of Porgy and Bess, so I'm a little bit out of my element here, but I'll answer as best I can.
Looking at Wikipedia, it looks like the original production premiered in 1935, which means it will be public domain on Jan 1, 2031. Whatever version of the show premiered in 1935 will go into the public domain then, and there is no way to extend the copyrightfor that version.That means the song arrangements, the book, etc.
Now, it looks like the 2011 version has a new book adaptation, which makes the collective show a new work. So that particular version will have a new copyright that will expire in 95 years. If the songs were also newly arranged, depending on how substantively different they are from the originals, the copyrights on the new arrangements will also expire in 95 years.
However, the original production from 1935 will still expire on Jan 1, 2031, and after that you could freely create derivative works assuming they are based on the original songs/arrangements and book. At that point the Gershwin Estate could not stop you from producing the 1935 version, even though the 2011 version is still copyrighted."
Just asking this because I'm curious, even though I know you are saying you aren't the Porgy and Bess expert. But if the stipulations are based on performance, then does that mean, since the complete score of Porgy and Bess was not performed onstage until 1976, the complete score will not be in the public domain until 2070. Anyone know?
