I had a few drinks and I am (or I have a friend that is) a REALLY GOOD singer! Is it ok to sit in with you???

No.. for the love of all that is good, NO! Hey, we’re sure you or your friends are great singers. And you sound absolutely fantastic from your seats! But unfortunately for you, so many more people came to the show to see The NEW Dueling Pianos on the stage, so our answer will be ‘NO’ every time.
