Irving Burgie does not claim authorship in his website, nor is it included in the list of songs copyright to him at ASCAP. I thought it was done by him for Harry Belafonte; that is incorrect.
Gee, I thought the Burgie lyrics were good; I guess that in my old age I like "elevator music."

It seems that the lyrics a commonly known belong to the Bergmans & Luboff and/or Keith. Many performers listed, inc. Brothers 4; Harry Belafonte not included- did he ever record it?

"Yellow Bird" copyrights listed by ASCAP; for those curious about them.
