Input: Consider Input: Question: Who was older the year Dane appeared on Jackie Gleason's show, Otis Spann or Willie Dixon? Passage:By 1959, Louis Armstrong had asked Time magazine readers: "Did you get that chick? She's a gasser!" and invited her to appear with him on national television. She appeared with Armstrong on the Timex All-Star Jazz Show hosted by Jackie Gleason on January 7, 1959. She toured the East Coast with Jack Teagarden, appeared in Chicago with Art Hodes, Roosevelt Sykes, Little Brother Montgomery, Memphis Slim, Otis Spann, Willie Dixon and others, played New York with Wilbur De Paris and his band, and appeared on The Tonight Show Starring Johnny Carson as a solo guest artist. Other national TV work included The Steve Allen Show, Bobby Troup's Stars of Jazz, and Alfred Hitchcock Presents. In 1961, the singer opened her own club, Sugar Hill: Home of the Blues, on San Francisco's Broadway in the North Beach district, with the idea of creating a venue for the blues in a tourist district where a wider audience could hear it. There Dane performed regularly with her two most constant musical companions: Kenny "Good News" Whitson on piano and cornet and Wellman Braud, former Ellington bassist.

Input: Consider Input: Question: How many years did Justin's father's party have power before being defeated in the 1979 election? Passage:Trudeau lived at 24 Sussex Drive, Ottawa, the official residence of Canada's prime minister, from his birth until his father's government was defeated in the federal election on May 22, 1979. The Trudeaus were expected to move into the residence of the Leader of the Official Opposition, Stornoway, at 541 Acacia Avenue in Rockcliffe Park, but because of flooding in the basement, prime minister Joe Clark offered them Harrington Lake, the prime minister's official country retreat in Gatineau Park, with the expectation they would move into Stornoway at the start of July. However, the repairs were not complete so Pierre Trudeau took a prolonged vacation with his sons to the Nova Scotia summer home of his friend, MP Don Johnston, and later sent his sons to stay with their maternal grandparents in North Vancouver for the rest of the summer while he slept at his friend's Ottawa apartment. Justin and his brothers returned to Ottawa for the start of the school year, but lived only on the top floor of Stornoway while repairs continued on the bottom floor. His mother purchased and moved into a new home nearby at 95 Queen Victoria Avenue in Ottawa's New Edinburgh in September 1979. The Trudeaus returned to the prime minister's official residence in February 1980 after the election that returned his father to the Prime Minister's Office.

Input: Consider Input: Question: What team did Gary Tallon play for the year Boulding turned professional? Passage:Boulding maintained his links with football and trained with Doncaster Rovers, and in 1998 he joined non-league Hallam near his home in Sheffield. His form at Hallam attracted the interest of a number of league clubs, and Boulding was offered a trial by Mansfield Town. He was given a contract by the Division Three side and turned professional in 1999, which brought an end to his tennis career. He made his debut with Mansfield in a League Cup game against Nottingham Forest on 11 August 1999 as a late substitute for Gary Tallon, before his first league game came three days later against Cheltenham Town. He had to wait until his 12th game as a professional to register his first goal when he scored in a 2–1 victory over Shrewsbury Town on 23 October. He eventually finished his first season with six goals with Mansfield coming 17th but 17 points above Carlisle United, the only side to be relegated out of The Football League.
