My understanding is that a song goes out of copyright 70 years (non-renewable) after the composer's death. That's the story in the UK, but surely with all the multi-national agreements which have dozens of countries as signatories, it would be the same for Europe & North America...? Wouldn't it? I'd be glad if someone could clarify this for me, because I've been informed by PRS (the Performing Right Society) that after 70 years of the composer's demise the piece is in the public domain. Apologies if this has been covered in other threads but I'm writing in a rush and don't have time for a trawl right now, and there are no nifty links above to help the energy-challenged. Thanks!
