After two unsuccessful years on the Southern nightclub circuit, Madden travelled to
Los Angeles, where a successful opening night at a
Beverly Hills nightclub led to a 10-week retention, and a recommendation by patron
Frank Sinatra to
Ed Sullivan, who signed Madden for three nights on
The Ed Sullivan Show. These appearances led to his first real acting engagement, a spot on
Camp Runamuck, in 1965. Madden first gained national notice as a milk-drinking, confetti-throwing sad sack on ''
Rowan & Martin's Laugh-In from 1968 to 1969. However, he became better known worldwide for his role as Reuben Kincaid, the harried manager/agent for The Partridge Family (1970–1974). Partridge'' co-star
Danny Bonaduce, whom Madden took into his home during Bonaduce's family's domestic strife, has said that he owes a lot to Madden. In 1976, he appeared in
Eat My Dust!, the first movie developed by
Ron Howard. Madden also made guest appearances on other television series, such as
Bewitched,
Happy Days,
The Love Boat,
Barney Miller (1978, episode: "Eviction", parts 1 and 2) and
Fantasy Island. He had a recurring role on
Alice as Tommy's basketball coach Earl Hicks, a regular at Mel's Diner. Madden began voicing several characters on
Focus on the Family's children's radio drama
Adventures in Odyssey in the late 1980s. In 1990, he received his own regular character in the curmudgeonly window-washer
Bernard Walton, a character he continued to play until 2008. In 1992, he reprised his role of Mr. Kincaid for a sketch on an episode of
The Ben Stiller Show. Two years later, he appeared with Bonaduce in an episode of
Married... with Children. In 1995, Madden appeared on the sitcom
Boy Meets World in the episode "Rave On". His last guest appearance was on
Sabrina the Teenage Witch, where he played Dr. Egglehoffer along with other former
Laugh-In cast members. Madden did voice-over work for numerous television and radio commercials, including the Corlick Sister ads for ''
Denny's from 1990 to 1993. Madden also narrated the opening title sequence for the FOX sitcom Herman's Head'' during the show's first two seasons. ==Personal life==
