Any time you listen or play a lot of music, all arranged by the same person, all the names mentioned plus others, even Sammy Nestico, you are going to hear phrases, licks or whatever that are similar to or just like another charts. But that is what makes it fun. You know when you are playing a Nestico chart, or someone else, without looking at the arranger/composer. In Ohio there was a golf course architect that did many public and private courses. I was playing at a state park course and asked if so and so had anything to do with the design, and I was correct. However, sometimes phrases can be overworked, especially when they are in the same chart.
But again, that's what music is all about. Being able to play great charts arranged and played by the best in the business. So what if they may have some similar notes, enjoy them.
Next time you play a new chart, don't look at the arranger, see if you can figure out who did it.
