Benson, spun-off from the controversial late 70's sitcom, Soap, proved to be a far more popular series than its parent. One example is a Christmas episode, courtesy of Frank Pilato. DiDi Conn (later of Shining Time Station) is on the piano for the medley at the end of the show. Just wait 'til you get to the ending, and Benson himself (Robert Guillaume) sings "O Holy Night".
Enough said! Rating: A.
