I'm The Japanese Sandman
I'm The Japanese Sandman is a song from 1920, composed by Richard A. Whiting and with lyrics by Raymond B. Egan.
The song is about a sandman from Japan, who exchanges yesterdays for tomorrows. The number has a very Oriental atmosphere, and is similar to many other songs from the interbellum who sing about a dreamy, exotic setting. The song has been covered many times.
Zappa sings a line from the song in A Little Green Rosetta: "Rang Tang, Ding Dong, I'm the Japanese Sandman".
