Question: Question: What age was Tony Backhouse the year that he cowrote "Some Day"? Passage:Jenny Morris was born in Tokoroa, New Zealand and grew up in Hamilton with three brothers (Alistair, Rhys and Tam) and four sisters (Maxine, Bronte, Joanne and Shanley). Morris wrote a poem on the Vietnam War when she was 12 and used her sister's guitar to put it to music. Morris has stated that her influences include Aretha Franklin and Dusty Springfield. Her first professional performance was at age fifteen, at Andersons Theatre Restaurant, in Hamilton. In 1976 she became a singer with How's Your Father, who were finalists in the 'National Battle of the Bands'. She began working as a Home Economics teacher for two years at a high school near Wellington. Late in 1978 Morris joined an all-girl group, Wide Mouthed Frogs in Wellington, performing lead vocals. Fellow members were Kate Brockie on lead vocals, Andrea Gilkison on guitar, Tina Matthews on bass guitar, Bronwyn Murray on keyboards and Sally Zwartz on drums. In 1979 they released the track, "Some Day" for the compilation album, Home Grown Volume One; "Some Day" was cowritten with Tony Backhouse, guitarist of fellow Wellington band, The Spats, which also had a track, "Young Ladies in Hot Cars", on the compilation.

Question: Question: What is the birth date of the other Polish RSDLP delegate who didn't go to London? Passage:Yakov Hanecki was born in Warsaw, then in the Russian Empire, the son of Stanislav von Furstenberg, a beer manufacturer of German descent, who had adopted Poland as his homeland. In 1896 he joined the Social Democracy of the Kingdom of Poland (SDKP - later the Social Democracy of the Kingdom of Poland and Lithuania (SDKPiL)) led by Rosa Luxemburg and her lover, Leo Jogiches. He moved to Germany in 1901 and studied in rapid succession at Berlin, Heidelberg, and Zurich universities. From 1902, he was a professional revolutionary, normally based in Cracow, under Austrian rule, organising the transport of illegal literature across the Russian border. In August 1903, as a member of the Main Administration of the SDKPiL, he was one of two Polish delegates to the Second Congress of the Russian Social Democratic Labour Party (RSDLP) in Brussels. The Congress later adjourned to London, under pressure from the Belgian police, and there the RSDLP split into its Bolshevik and Menshevik factions, but Hanecki and the other Polish delegate, Adolf Warski, did not make the journey to London, having failed to agree terms on which the RSDLP and SDKPiL could collaborate.

Question: Question: Where was the person born who plays Ernst Stavro Blofeld ? Passage:The story sees Bond pitted against the global criminal organisation Spectre and their leader Ernst Stavro Blofeld (Christoph Waltz). Bond attempts to thwart Blofeld's plan to launch a global surveillance network, and discovers Spectre and Blofeld were behind the events of the previous three films. The film marks Spectre and Blofeld's first appearance in an Eon Productions film since 1971's Diamonds Are Forever; a character resembling Blofeld had previously appeared in the 1981 film, For Your Eyes Only, but, because of the Thunderball controversy, he is not named, nor is his face shown. Several James Bond characters, including M, Q and Eve Moneypenny return, with new additions Lea Seydoux as Dr. Madeleine Swann, Dave Bautista as Mr. Hinx, Andrew Scott as Max Denbigh and Monica Bellucci as Lucia Sciarra.

Answer:
The story sees Bond pitted against the global criminal organisation Spectre and their leader Ernst Stavro Blofeld (Christoph Waltz)
