Lyricist Howard Eisenberg has written many books, hundreds of magazine articles, and many scripts for TV, radio, and theater. Once, during a book tour, he bought picture postcards of zoo animals and wrote fill-in-the-blank poems to mail to his grandchildren. Through a collaboration with composer and friend Sherwin Kaufman, these poems have been set to music to create The Guess Who Zoo.

Composer Sherwin Kaufman, grandson of legendary author-humorist Sholom Aleichem of Fiddler on the Roof fame, started his musical career as a classical pianist. He retired from a long and successful career as a physician, and is now an award-winning ASCAP composer and lyricist.

He has earned 25 Gold and 12 Platinum records.
