do not be an impertinent musical saxophone person

I should like to point you towards a charming but assertive etiquette lesson from Jenny Vaudeville alumni The Two Man Gentleman Band.

"Since publishing our first Lesson in Etiquette," writes Andy Bean, "our lives generally and musical performances specifically have been most pleasantly devoid of the impertinent interruptions described therein. Our conclusion? The people must read our electronic missives and adjust their behavior accordingly! What a pleasant surprise."
