Question: How many seasons did the television show that Earl Gaines appeared on air?  Passage:Breaking away from the confines of the group, Gaines became part of the 1955 R&B Caravan of Stars, with Bo Diddley, Big Joe Turner, and Etta James. Their tour culminated with an appearance at New York's Carnegie Hall. Without any tangible success, Gaines recorded for the Champion and Poncello labels for another few years, as well as joining Bill Doggett's band as lead vocalist. In 1963, he joined Bill "Hoss" Allen's repertoire of artists, and by 1966 had issued the album The Best of Luck to You, seeing the title track reach the Top 40 in the US R&B chart. He appeared on the television program The !!!! Beat, and later released material for King and Sound Stage 7, including his cover version of "Hymn Number 5". Recordings made between 1967 and 1973 for De Luxe were reissued in 1998. On many of his De Luxe recordings in the late 1960s and early 1970s, Gaines was backed by Freddy Robinson's orchestra.

Question: What kind of aircraft were leased? Passage:In addition to withdrawing from the prestigious long-haul routes to New York and Los Angeles after only 18 months, other specific measures the airline took at the time to ensure its survival included dropping all scheduled flights to Belfast, Copenhagen, Gibraltar, Ibiza, Málaga, Palma de Mallorca and Tunis, indefinitely suspending scheduled services on the Glasgow—Southampton route as well as cutting the number of frequencies on the Gatwick—Glasgow and Gatwick—Edinburgh routes from six to four daily round trips. Two surplus aircraft were leased out to Air Malta and Austrian Airlines respectively for the duration of the 1975 summer timetable period. Another aircraft was stationed at West Berlin's Tegel Airport during the month of July of that year to fulfill a short-term charter contract to carry Turkish migrant workers to and from Istanbul on behalf of a local tour operator. BCal also decided to increase its 707 freighter fleet from one to four aircraft and to acquire a five-seater Piper Aztec to serve the rapidly growing executive charter market. These changes left BCal with 25 operational aircraft for the 1975 summer season. To reduce operating costs further, the airline decided to contract out its scheduled operations between Gatwick and Le Touquet to BIA. The reason for replacing BCal's One-Eleven 200 jet aircraft on this route with that airline's Herald turboprops at the beginning of the 1975 summer timetable period was the high price of jet fuel, which had made BCal's own jet aircraft operations uneconomic.

Question: What party controlled the legislative branch of government the  Dixiecrats hoped to force a contingent election in 1948? Passage:Truman had acceded to the presidency in April 1945 after the death of Franklin D. Roosevelt. Defeating attempts to drop him from the ticket, Truman won the presidential nomination at the 1948 Democratic National Convention. The Democratic convention's civil rights plank caused a walk-out by several Southern delegates, who launched a third-party "Dixiecrat" ticket led by Governor Strom Thurmond of South Carolina. The Dixiecrats hoped to win enough electoral votes to force a contingent election in the House of Representatives, where they could extract concessions from either Dewey or Truman in exchange for their support. Truman also faced a challenge from the left in the form of former Vice President Henry A. Wallace, who launched the Progressive Party and challenged Truman's confrontational Cold War policies. Dewey, who was the leader of his party's moderate eastern wing and had been the 1944 Republican presidential nominee, defeated Senator Robert A. Taft and other challengers at the 1948 Republican National Convention.
