Input: Question: Which of the two Texas stations that continued to broadcast Lauck and Goff began airing programs the earliest? Passage 1:Brandon was born in Bradenton, Florida, attended elementary school in Elfers, and attended Bayonet Middle School and River Ridge High School in New Port Richey. He later attended the University of Florida, where he received a degree in English, and Brandon also received a Master's degree in fiction writing from Washington University in St. Louis. After writing Arkansas Brandon gained the attention of Barry Hannah, who nominated him for the John and Renee Grisham Writer-in-Residence program at the University of Mississippi. He then went on to work a series of warehouse and factory jobs before holding a one-year fellowship at the Gilman School and teaching at Hamline University in Minnesota. He was also the GQ's SEC College Football analyst. Self-proclaimed worshiper of Joy Williams.
 Passage 2:Swayne spent much of his childhood in Liverpool, and began composing at a young age. He was educated at Ampleforth College and at Cambridge University, where he worked with Raymond Leppard and Nicholas Maw before spending three years at the Royal Academy of Music as a student of Harrison Birtwistle, Alan Bush and, once again, Maw. During the years 1976 to 1977 he attended several of Olivier Messiaen's classes at the Paris Conservatoire and from 1981 to 1982 made a study visit to the Gambia and southern Senegal – a formative experience he put to creative use as composer-in-residence to the London borough of Hounslow, 1980–83. Together with his second wife, the Ghanaian, Naaotwa Codjoe, he lived in a village near Accra, Ghana, from 1990 to 1996; he has now settled in London. Swayne is a cousin of Elizabeth Maconchy.
 Passage 3: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. Miles Laboratories, manufacturers of Alka-Seltzer and One-A-Day Vitamins, became the longest-running sponsor, backing the program from 1941 until 1948. Over the course of its life, Lum and Abner appeared on all four major radio networks: NBC, Mutual, CBS and ABC (formerly NBC Blue).
