Yeah. He had a name for everybody. He wrote for individual players. That way they kept a good span for - never wrote anything too high for Ray Nance. All the high notes are done by Cat Anderson. So it is personalized. I learned to do that. It saves a lot. I still do that today. In fact I'm getting a score sent in from L.A., a thing called Opus No.6. I'll been rehearsing with a band Monday. That's a full band. I gave the copyist a  full sketch. He learned from that. I did that a couple weeks ago. If I didn't have a full sketch and had a major score, it would take me a long time. This way [?].
