Trivia: The daughter of Rick Nelson (son of Ozzie and Harriet Nelson) and Chris Harmon (daughter of football legend Tom Harmon and sister of actor Mark Harmon), Tracy Nelson made her film debut at age five as one of Henry Fonda's daughters in Yours, Mine and Ours (1968). Her movie career didn't really pick up until her teens, when she began appearing in such films as Footloose (1982) and Down and Out in Beverly Hills (1986). Before that, Tracy was seen as Jennifer DeNuccio, a zoned-out valley girl on the 1982 "teen-misfit" TV sitcom Square Pegs. Seven years later she was playing Sister Stephanie, a spunky young nun with a gift for sleuthing and a predisposition for disguise on the weekly television crime drama Father Dowling Mysteries. Between 1987 and 1989, Nelson battled with Hodgkins disease. She has continued her film career through the 1990s, appearing in television series and made-for-television movies.

Trivia: While growing up in Chicago, Tom Bosley dreamed of becoming the star left-fielder for the Cubs. As it turned out, the closest Bosley got to organized athletics was a sportscasting class at DePauw University. After additional training at the Radio Institute of Chicago and two years' practical experience in various dramatic radio programs and stock companies, he left for New York in 1950. Five years of odd jobs and summer-theater stints later, he landed his first off-Broadway role, playing Dupont-Dufort in Jean Anouilh's Thieves' Carnival. Steadier work followed at the Arena Theatre in Washington, D.C.; then in 1959, Bosley landed the starring role in the Broadway musical Fiorello!, picking up a Tony Award, an ANTA Award, and the New York Drama Critics Award in the bargain. In 1963, he made his film bow as Natalie Wood's "safe and secure" suitor Anthony Colombo in Love With the Proper Stranger. Occasionally cast as two-bit criminals or pathetic losers (he sold his eyes to blind millionairess Joan Crawford in the Spielberg-directed Night Gallery TV movie), Bosley was most often seen as a harried suburban father. After recurring roles on such TV series as That Was the Week That Was, The Debbie Reynolds Show, and The Sandy Duncan Show, Bosley was hired by Hanna-Barbera to provide the voice of flustered patriarch Howard Boyle on the animated sitcom Wait Til Your Father Gets Home (1972-1973). This served as a dry run of sorts for his most famous series-TV assignment: Howard Cunningham, aka "Mr. C," on the immensely popular Happy Days (1974-1983). The warm, familial ambience of the Happy Days set enabled Bosley to weather the tragic death of his first wife, former dancer Jean Elliot, in 1978. In addition to his Happy Days duties, Bosley was narrator of the syndicated documentary That's Hollywood (1977-1981). From 1989 to 1991, he starred on the weekly series The Father Dowling Mysteries, and thereafter was seen on an occasional basis as down-to-earth Cabot Cove sheriff Amos Tupper on Murder, She Wrote. Reportedly as kind, generous, and giving as his Happy Days character, Tom Bosley has over the last 20 years received numerous honors for his many civic and charitable activities.
