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: In which country did the Essex v Northamptonshire match take place? Passage:The Essex v Northamptonshire match was played at Valentines Park, Ilford 17 to 20 May. Northamptonshire won the toss and decided to bat, scoring 215 all out with a top score of 49 by Vince Broderick while Essex's Test leg break and googly bowler Peter Smith took four for 65. By close of play on Saturday, Essex had replied to 170 for 4 with opener Chick Cray on 90 not out. He completed his century, exactly 100, on Monday morning and Essex went on to total 267 all out. Northamptonshire were 219 for 5 at the close on Monday evening with their veteran batsman John Timms on 90 not out. Timms was out for 112 on Tuesday morning and Peter Smith completed ten in the match by taking six for 84 in the Northamptonshire total of 291. Essex therefore needed 240 to win with ample time left on the final day. They had a good stand of 103 for the fourth wicket between Frank Vigar (60) and Len Clark (64) but spinners Broderick and Bertie Clarke kept picking up the wickets and Essex were still ten behind when the ninth went down. The last pair were captain Tom Pearce and wicketkeeper Tom Wade who managed to level the scores before Wade was bowled by Clarke to tie the match.
