Tom Lehrer's material is well known among the folkies we hang out with. If someone does one of his songs, several people will surely follow with others. We even heard several of his creations at a folk music club in Yorkshire.

We often sing Pollution in schools during our program on Environment and Ecology and, yes, we often mess up the chords.

We heard an interview with him on the radio many years ago and he said that he has written a total of less than forty songs. Nearly all of them are well known. Not many songwriters can say that.

Flanders and Swann are pretty well known, too. There was a question on Jeopardy within the last week involving Glorious Mud.
