Does that mean we can't even have one SMALL glass of red wine (I'm thinking an Aussie shiraz) with our (steak?) dinner? Other than that, I totally agree - you offered the whiskey, and should not allow any of us to touch it until after the last (flash enhanced?) photo run-by. If you will keep me posted as to the expected number of passengers, I will bring only enough wine for one glass apiece.
People used to buy me a beer or three to get me to STOP singing, but my daughter has been invited to continue with the U.C. Davis choir even though she graduated well over a year ago. When she sang in the Ventura County Symphony youth choir, the director said I had a good voice but it was "untrained". And I promise not to bring my cajun washboard!
Besides, the whistle will drown us out anyway!
