The earliest known train songs date to two years before the first public railway began operating in the United States . "The Carrollton March", copyrighted July 1, 1828, was composed by Arthur Clifton to commemorate the groundbreaking of the Baltimore & Ohio Railroad . Another song written for the occasion, "Rail Road March" by Charles Meineke, was copyrighted two days after Clifton's, one day before the July 4 ceremonies. The number of songs that have appeared since then is impossible to determine, not only because of the difficulties in documenting the songs but also in defining the genre.

Dane taunts the Joint Chiefs in the Pentagon ... Written by Angus Brewer
In case it isn’t obvious: SPENDING THIS MUCH OF TOP LINE REVENUE ON SALES AND MARKETING IS NEW . This is not business as usual. The higher gross margins generated by software and SaaS are enabling unprecedented spending on sales and marketing below the gross margin line. I read a study recently in which two economists tried to advance their preferred narrative by citing high gross margins that can exist in business today. Yes they are high in SaaS. No, that is not the whole story. Spending below the gross margin line on sales and marketing is far higher.
