The music is an eclectic, full-course buffet, from lip-synced performances by Creedence Clearwater Revival to the chart-topping ballads of Neil Diamond and Gordon Lightfoot to the defiantly leftist folk of Pete Seeger and Buffy Sainte- Marie. Unexpected highlights include Joe Cocker's sublime rendition of the Beatles' "Something" and Frankie Laine's emotional delivery of "Lord, You Gave Me a Mountain." Throughout, Steinberg is like a protestor with a lost cause, and by the time he's joined by cohost Groucho Marx for the mesmerizing final show, he's lost all pretense of mainstream propriety, and it's TV history like nothing before or since. A full menu of 21 bonus songs is icing on a bittersweet cake, from one-hit-wonders Zager & Evans ("In the Year 2525") to an impassioned "Try (Just a Little Bit Harder)" by Janis Joplin, whose own fate would soon echo that of this remarkable, short-lived TV show. --Jeff Shannon
