Dear Bill:
Down in North Carolina, your “Spring is sprung, grass is riz” poem has been a favorite for years. I don’t know the name of the author, but I object to seeing it published over somebody else’s initials.

18 January 1976, New York Times, “Talking Brooklyn in Joisey” by Mario Pei, pg. 328:
It was ultimately sublimated into exalted verse in what is described as “The Brooklyn National Anthem,” although its lack of nationalistic features makes it applicable to Hoboken and Jersey City as well:

“De spring is sprung,
De grass is riz;
I wunneh wear de flowers is.
De boid is on de wing --”

“Absoid! De wing is on de boid!”
