If you like Tom Lehrer then you might also enjoy his British contemporaries Flanders & Swann in "At the drop of a hat" and other albums.
With rare exceptions ("The laws of thermodynamics") they didn't write about the sciences, but they were musically a bit more sophisticated and just as witty.
Their satire was far less biting but was present. Although Michael Flanders did monologue: "The purpose of Satire, it has been rightly said, is to strip off the veneer of comforting illusion and cosy half-truth - and our job, as I see it, is to put it back again." :)
I recommend their delightful animal song "The Sloth" as having pertinence to my fellows in the HN audience who have trouble with procrastination...
