Can we wave the right number of fingers to indicate the tune is in "D"?

And if you happen to be in C or G will that put you off (tee-hee)?

Of course if an american passed by tehn he may need to be told teh key is "G".

Did I mention that I took key signatures as a divine message indicating that C Sharp House ought really to be seven flats?

THis weekend had better be good!
