A September of Demento continues with “Poisoning Pigeons In The Park”- by Tom Lehrer. Tom Lehrer who is still alive-he’s now 92- had a career as a singer-songwriter, satirist and mathematician. He pretty much retired from music 50 years ago to concentrate on teaching mathematics and musical theater at the University of California. “Poisoning Pigeons In The Park” was one of his most well known song.
