As an avid viewer of the usually wonderful series Unsung, sometimes I scratch my head over their choices. On what planet are George Clinton and Isaac Hayes considered unsung? I’ve no idea, but Oakland-bred soul man Lenny Williams surely satisfies the criteria. While the man has spent most of his life writing and singing popular music with the influential funk band Tower of Power (“What is Hip,” “Soul With a Capital S”) as well as his own solo hits “Choosing You” and classic midnight baby making anthem “’Cause I Love You,” many folks still have a hard time recognizing the face behind that richly beautiful voice.
