Chas, good points. I might add, though, that probably close to 100 percent of people who own or work in recordings studios are 100 percent ignorant regarding arrangers. They wouldn't know one if it bit them in the butt.
I'm betting a good keyboardist that fully understands arrangers could do recordings in the same studio and the public, listening to the finished product, could never tell the difference!
Good to hear from you, btw!
