i think wrinkly ****er cliff richards ran into legal properties holding on to royalties of records he released 50 years ago...
I think he lost as well, although I didn't keep up with what happened

Basically because he released the record 50 years back he stopped making money of it. So i think its 50 years from release in the UK, whether you're still alive or not. Seems a trifle unfair...
