Tom Lehrer has been my go-to source of acerbic wit and brilliant satire since I first encountered him when attending the Norwegian University of Tecnology and Science; a group I joined there held Lehrer in high esteem and I, too, was blown away by how timeless a lot of his songs were; a lot of satire ages very quickly, but chances are my unborn grandchildren will laugh hysterically to 'Who's Next?' or 'Wernher von Braun' after doing the mid-21st century equivalent of googling to find out who WvB was, of course.

Godspeed, Tom. This has been a rough week - three of the heroes of my formative years have checked out of existence - Lehrer, Ozzy and author Ingvar Ambjørnsen. Sigh. Who's next?
