He's still around and has a web site http://www.tomlehrer.org. I'm not sure how much is his doing and how much is a tribute to him. I do know it includes a clip of Daniel Radcliffe singing the elements song. Puff! Puff!
For more on Tom Lehrer see Wikipedia, http://en.wikipedia.org/wiki/Tom_Lehrer.
Garrison Keillor and the Prairie Home Companion are keeping some of his songs going. This past Saturday the Digiallonardo Sisters did Tom Lehrer's "Hanukkah in Santa Monica".
