Writer and humorist Christopher Cerf has been associated with the Children's Television Workshop since 1970, developing products, producing music album and writing parodies of rock-and-roll songs for Sesame Street.
Cerf writes children's songs for Sesame Street and helped launch the humor magazine the National Lampoon. In 1978 he co-edited the journalistic parody "Not the New York Times." His most recent humor book is "The Book of Sequels," a spoof of current trends in the publishing and film industries.
Christopher Cerf's educational songs for children are featured on the television show Sesame Street. He tells Fresh Air's Terry Gross about how he chooses his subject material and the popular songs he pays tribute to. An album of Sesame Street music, titled Born to Add, features many songs he wrote and performed.
