Lehrer's songs--cynical and sarcastic, Tin Pan Alley style black humor, as if Lenny Bruce teamed up with Lerner and Loewe--were welcome assaults on the bland conformism of their day, the prepsychedelic early 1960s; we could use some of that biting comedy in the yuppified 80s, and David Whitehouse and Andy Miller, whose songs form the spine of this brief show, seem willing to oblige.
