The source (Ratcliff Highway-3), most likely, was C. Fox Smith. Stan was very familar with her work and her anthology A SEA CHEST was available. I borrowed my 1920's copy from the Boston Public Libary last weekend. Now I know I need to find one on the used book websites.
I especially enjoy the "words of wisdom" expressed in this song, based on extensive sampling of the wares available along that infamous street. Look sharp, me lads!
I won't swear by the traditional tune but it's a logical one.
