John Astin guest stars as Sidney Rose, a reclusive multimillionaire who summons the Partridges to his mountain retreat for a private concert. Shirley (Shirley Jones) tries to persuade Sidney to come out of his shell and return to the outside world, which he ultimately does--but not before adopting a series of silly disguises to keep the public and the press at arm's length. Song: "One Night Stand" (Trivia note: John Astin had previously costarred with Shirley Jones' future husband Marty Ingels in the 1962 TV sitcom I'm Dickens--He's Fenster).
