The Jackson Five perform "The Life of the Party," returning for the musical finale, a rousing salute to such musical groups as The Mills Brothers, The Andrews Sisters, The Coasters, And The Supreme's. Guest William Conrad shows his versatility by singing a "Movies Were Movies" tribute to silent-comedy stars, then slipping into a mime routine as Oliver Hardy. He next shows his flair for comedy in a sketch with Harvey (they're doctors and golfing buddies). But the highlight is his portrayal of Willy, the widowed Mama's wealthy suitor in the "Family" sketch titled "The Gentleman Caller." (thetvdb.com)
