Update...

I called the area office of the American Cancer Society and asked them directly about private clubs.

The PR person explained that there is still some wording that has to be clarified with regard to Private clubs as they are not "open to the public."

She stated that the ACS will be participating in the special rules for these type clubs and that while she doesn't expect smoking to be banned in those places, she felt very confident that additional measures be required by law for such places to protect employees, guests, musicians, etc...

Hmmm...
