Bill, thank you, the video brought out things that I have been trying to say, but a more elegant way.

In my explanations I have left out one important thought, people who have played in a band with other musicians are more likely to do what the video pointed. Start playing at the right time, people like Don, Tony and Donny do that without thinking. They are also more aware of what the style is doing.

Controlling the style:
Helpers in order of importance. Registrations, mixer, and the pads.

I picture Tony with his band; he listened for a lead-in for him to sing, or solo. (like listening to the style) He did not want all the same instruments to keep playing, they would have been in his way.

There is more, much more, so thanks to Bill we may listen to styles differently now.

PS, one of the reasons organs have lost their popularity was demonstrated in the video; playing big band music with organ sounds. Wersi demo people never did that
