My God Man, It's Gene's show. He can do whatever he wanted. Did GR pit a soprano in there? A trumpet couldn't play that part and a violin would be too weak. It's a song for a Wagnarian singer. He used plenty of Courage's music. IMO, the words would have made it intreguing if and maybe he had got them right but you're complaining about him crossing borders when he created those borders.
He technically had the right because he created Star Trek, but it is still considered a sleazy thing to do. They reused Courage's scores from season one, but Courage didn't do anything more with GR. GR had nothing to do with the orchestrations. That wasn't his job.
That's what I mean. GR was just making the most of Courage's soprano who was already hired. Who was better at writing words, Gene or Alex? The minor seventh of the opening seems to be saying Star Treeek to me... but heck this is fourty years later, but if he could have been sued, I'm sure he would have by now. The subject of auther credit has also come up on episodes like the Sargon episode where Gene took story credit and the writer is all upset to this day which in my mind is a more legitimate claim but I don't know the details of that but I'm assuming he's just looking for on screen credit since there can't be any more royalties at this point, can there? Now had the updated versions had fixed that with a premise by so and so, that would have been great, but I'm chalking it up to oversight and that greedy lawyer of his who is remarkably innocent in any of this.
