[Q]: 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.

[Q]: Question: On what date did Morsi take office? Passage:Following the Egyptian revolution of 2011 as part of the regional Arab Spring protests, Mubarak was ousted and the following year Mohamed Morsi who is backed by the Muslim Brotherhood won Egypt's first democractic elections. In 2013 Morsi was removed from power in a coup led by Abdel Fattah el-Sisi. Sisi has called for religious tolerance and has cracked down and banned the Muslim Brotherhood. He has closed thousands of mosques and has banned 'burkinis' on some beaches. A The Economist report in 2017 stated that Egyptians were turning more secular again, with supporters of sharia law dropping by more than half since 2011, people praying less than before, and gender equality now being widely accepted. The government has also acted to preserve its Jewish heritage through the restoration of the abandoned Eliyahu Hanavi Synagogue in Alexandria in 2017.
