Happy Birthday, Tom Lehrer

Tom Lehrer was born 81 years ago today. A mathematician by trade, but best known as a singer-songwriter, Lehrer is someone who is known by many generations. His comic songs include 'The Elements', the 'Masochism Tango' (very racy for 1950s America) and 'Poisoning Pigeons in the Park' (which, I think, is my favourite).

Here's wishing him a very Happy Birthday.
