Influenced mainly by musical theater Lehrer's style consists of parodying various forms of popular song. For example, his appreciation of list songs led him to set an unordered list of the chemical elements to the tune of Gilbert and Sullivan's "Major-General's Song".
Author Isaac Asimov recounted in his second autobiographical volume In Joy Still Felt of seeing Lehrer perform in a Boston nightclub on October 9, 1954, during which Lehrer sang very cleverly about Jim getting it from Louise, and Sally from Jim, "and after a while you gathered the 'it' to be venereal disease likely this was, "I Got It From Agnes". Suddenly, as the combinations grew more grotesque, you realized he was satirizing every perversion known to mankind without using a single naughty phrase. It was clearly unsingable (in those days) outside a nightclub." Asimov also recalled a song that dealt with the Boston subway system, making use of the stations leading into town from Harvard, observing that the local subject-matter rendered the song useless for general distribution. Lehrer subsequently granted Asimov permission to print the lyrics to the subway song in his book. "I haven't gone to nightclubs often," said Asimov, "but of all the times I have gone, it was on this occasion that I had by far the best time."
