Trivia: A singer almost from the time she learned to talk, American actress Shirley Jones was entered by her vocal coach in the Miss Pittsburgh contest at age 18. The attendant publicity led Jones to an audition with Rodgers and Hammerstein for potential stage work. Much taken by Jones' beautifully trained voice, the producers cast her as the leading lady in the expensive, prestigious film production of their theatrical smash Oklahoma! (1955). In 1956 Jones starred in another Rodgers and Hammerstein film adaptation, Carousel; this and her first film tended to limit her to sweet, peaches 'n' cream roles for the next several years. Thankfully, and with the full support of director Richard Brooks, Jones was able to break away from her screen stereotype with her role as a vengeful prostitute in Elmer Gantry (1960) -- a powerfully flamboyant performance that won her an Academy Award. Alas, filmgoers preferred the "nice" Shirley, and it was back to goody-goody roles in such films as The Music Man (1962) and A Ticklish Affair (1963) -- though critics heartily praised Jones' performances in these harmless confections. It was again for Brooks that Shirley had her next major dramatic film role, in 1969's The Happy Ending, which represented one of her last movie appearances before her four-year TV stint as the glamorous matriarch of The Partridge Family. This popular series did less for Shirley than it did for her stepson, teen idol David Cassidy, but The Partridge Family is still raking in ratings (and residuals) on the rerun circuit. Her unhappy marriage to the late actor Jack Cassidy long in the past, Jones found domestic stability as the wife of actor/agent Marty Ingels, with whom she wrote a refreshingly candid dual biography. The actress also played a recurring character on The Drew Carey Show (1998-1999), and appeared in numerous documentaries throughout the 2000s. Jones had a supporting role in 2006's Grandma's Boy, and guest roles on shows like Cougar Town and Raising Hope.

Trivia: Stuart Margolin was a published writer and off-Broadway playwright before he was old enough to vote. The pinch-faced, curly-headed Margolin began showing up in character parts in 1966, in films like Women of a Prehistoric Planet and TV series like Occasional Wife. He was a staff writer and member of the acting ensemble on the popular sitcom anthology Love American Style, which ran from 1969 through 1974. In 1971, Margolin co-starred on the western series Nichols, launching his long friendship and professional association with actor James Garner. He went on to win two Emmy awards for his portrayal of mildly larcenous Angel Martin on Garner's long-running (1974-80) series The Rockford Files; played Philo Sandine on the 1981 retro Garner TV vehicle Bret Maverick; and guest-starred on the first episode of Garner's short-lived "dramedy" Man of the People (1991). Stuart Margolin turned to directing in the 1980s, beginning with (inevitably) a brace of James Garner TV movies, The Long Summer of George Adams (1982) and The Glitter Dome (1984)); he has since helmed two theatrical features, Paramedics and Donna d'Onore (both 1990).

Trivia: A performer whose career soared and peaked in the early '70s, multifaceted entertainer David Cassidy dramatically redefined the term "teen idol," as others including Paul Anka and Neil Sedaka had before him. In his heyday, Cassidy culled an untoward number of admirers, including legions of starstruck teenage girls. The son of actors Jack Cassidy and Evelyn Ward (and the stepson of Shirley Jones), David landed his first major break on the blockbuster '70s musical sitcom The Partridge Family (1970-1974), opposite Jones, Susan Dey, and Danny Bonaduce. Based very loosely on the experiences of the real-life family vocal band the Cowsills, the now-iconic series told of a widowed mother and her brood of rowdy kids, who became national pop stars overnight, and eked out a life touring in a colorful schoolbus and performing all over the country. Cassidy -- 20 years old when the series premiered -- played the eldest Partridge boy, 16-year-old David. Series producers took advantage of the program's success by marketing the Partridges as a real-life recording group, fronted by David (who was not a professional musician); this worked, and brought Cassidy Grammy Awards and the largest celebrity fan club in the history of recorded music. The triumphs were somewhat short-lived, however, and by 1975 (a year after Family folded) Cassidy's popularity with the younger market had declined, as new and fresher talent took his place. He responded by branching out into acting roles, in films such as A Chance to Live (1978), The Narc (1978), and The Night the City Screamed (1980), and in time established an agreeable presence as a musical theater star, on Broadway and in London's famed West End.Cassidy's overall popularity rebounded in the mid- to late '90s. Thanks in no small part to a nostalgia craze and to presence on VH1, he landed an assignment opening the 75-million-dollar show EFX at the MGM Grand, which in turn gave him the clout to mount and produce his own revue in Vegas, a tribute to Sinatra and co. christened The Rat Pack Is Back (1999). In the following decade, Cassidy began touring once again, signed a new record deal, and issued a series of albums including Then and Now (2001) and Touch of Blue (2003). Busy as ever, he topped TV GUIDE's list of the 25 Greatest Teen Idols in 2005.

Trivia: Red-headed, ruddy-faced American supporting actor Ken Swofford made his movie debut in 1964's Father Goose. Swofford hit his peak on television in the 1970s and 1980s, playing explosive, loudmouthed, stuffy types. He was brilliant as Winchell-like columnist Frank Flannagan in the weekly 1975 version of Ellery Queen, then went on to essay subtler variations of this character in Switch (1975-78) and The Eddie Capra Mysteries (1978-79). He was one of the singular delights of the syndicated version of Fame (1983-87), as the kids' perennial nemesis, vice-principal Morloch. Off camera, the affable Swofford got along famously with his young Fame co-stars, and was one of the series' biggest boosters on the promotional-tour circuit. More recently, Ken Swofford was seen in the recurring role of Lt. Capalano in Murder She Wrote (1984-96).
