Sorry to bring up copyright again, I know we get pretty fed up with it, but I really would appreciate opinions on this one. Our busiest area of work is music for dance - specifically Ballet. So it's music on official lists, music for exams, music for different styles, even music for the exam parts where they must identify the difference between a tango and a tarantella. We've been approached to produce some different types of music, and specifically Gershwin. There's a huge catalogue, but not all will work because of the rules on lengths and content- but lots will. My view on the rights are that George Gershwin, who wrote the music, died before WW2, so the 70 years after death rule which we have here in the UK makes the songs public domain. However, I see the same songs described in two ways. Music, George Gershwin, Lyrics, Ira Gershwin - who is NOT gone long enough to be public domain. My stand at the moment is that as our music contains only music and not lyrics, we're fine. However, many of the credits for these songs say Words and Music by George and Ira Gershwin. This is not quite the same. The Gershwin family protect their products strongly in some territories. I've been unable to get a categoric copyright opinion so far. We're going to do it - but I'd appreciate any opinions on the status of this music. Maybe anecdotal stories you may have heard or any absolutes you have knowledge of. It won't be a major money spinner, but just another income stream.
