Passage:Having moved to Los Angeles, Reeves took acting classes at the Lee Strasberg Institute, and appeared in the movie Fairy Tales, and on the television series Quincy, ME. Reeves also appeared on game shows such as Hollywood Squares. In 1977, with the help of former Motown producer Frank Wilson, Reeves became a born-again Christian, joining the Mt.

She then performed in a Broadway production of Ain't Misbehavin' and reunited with original members of the Vandellas in 1989 both on record (recording for the London-based Motorcity Records that year issuing the single "Step into My Shoes") and on tour. In 1995, Reeves and the Vandellas were inducted to the Rock & Roll Hall of Fame and were inducted to the Vocal Group Hall of Fame in 2003. Martha performed as part of the halftime show of Super Bowl XXXII in 1998, with her sisters, and current Vandellas, Lois and Delphine Reeves. In 2004, Reeves released her first album in 24 years, Home to You, with songs she wrote and produced herself except for a Billie Holiday cover and an updated version of her big hit, "Jimmy Mack". Between leaving the Vandellas and her solo career, Martha served as an early contributor to the music newspaper, Soul, for which she was honored for by the Black Women in Publishing organization. She was also honored for her best-selling 1995 autobiography, Dancing in the Street.

Question: Which of the two Texas stations that continued to broadcast Lauck and Goff began airing programs the earliest? Passage:When the Quaker contract expired, Lauck and Goff continued to broadcast on two Texas stations, WBAP (Fort Worth) and WFAA (Dallas). In 1933, The Ford Dealers of America became their sponsor for approximately a year. Horlicks Malted Milk, the 1934–37 sponsor, offered a number of promotional items, including almanacs and fictional Pine Ridge newspapers. During this period, the show was broadcast on Chicago's WGN (AM), one of the founding members of the Mutual Broadcasting System. Effective July 1, 1935, the program was also carried on WLW (Cincinnati, Ohio), KNX (Los Angeles, California), and KFRC (San Francisco, California). Along with The Lone Ranger, Lum and Abner was one of Mutual's most popular programs. In 1936, Dick Huddleston of Waters petitioned the United States Post Office to change the town's name to Pine Ridge. Postum cereal sponsored Lum and Abner in 1938–40, before Alka-Seltzer picked up the duo.

Over the course of its life, Lum and Abner appeared on all four major radio networks: NBC, Mutual, CBS and ABC (formerly NBC Blue).
