Here are the titles of the Harburg poems on the Mitchell Trio album, Slightly Irreverent:

On That Great Civilized Morning
Pentagonorreah
In The Merry Month of Mayhem
Yevtushenko?
Less Majeste
For The Man Of Extinction
Achtung!
Red, White And Blue Cross
Shall I Write A Letter To My Congressman?
Back To The Drawing Board

I believe that these and many more were later published in book form by Harburg.
