Lehrer is a singer-songwriter who accompanied himself on the piano. He is best known for the songs that he recorded in the 1950s and 1960 (while also lecturing on mathematics at Harvard among other colleges). Many were satirical, such as "Fight Fiercely, Harvard," a suggested fight song for his alma mater. Some dealt with social issues of the day, such as "Pollution" and "I Wanna Go Back to Dixie" (a highly unflattering view of the South during Integration), while others were offbeat black humor ("Poisoning Pigeons in the Park").
