by Sean CarruthersWhat worked twice is bound to work again, right? Bob Newhart's third comedy album doesn't deviate too far from the usual formula: Newhart adopts a persona and voices half of a conversation or gives a speech. There are a few exceptions, including the leadoff track, "Rocket Scientist," where he voices both sides of an interview, and part of the second side. It's all reasonably solid, but there aren't as many belly laughs on this one and it occasionally gets a bit more mean-spirited than properly fits Newhart's generally genial style -- in other words, it's not really an oversight that none of these tracks made it to the early best-of album.
