Question: In what year did the Ford Mustang appear as a race car in the United States? Passage 1:Appearing at the Gasteig in 2005, she performed Chopin's Piano Concerto in E minor with the Münchener Kammerorchester, conducted by Christoph Poppen. In 2008, Babor appeared in a recital at the Ushuaia festival playing works by Beethoven, Prokofieff, Schubert and Ginastera, and Mozart's Piano Concerto in C major, K. 482. In 2009, as part of the project Musik Werkstatt Jugend (youth music workshop), she played Rachmaninoff's Piano Concerto in C minor with the ensemble interculturel in concerts in Munich's Herkulessaal and in Rouen. In 2011, she was the pianist in a concert at the Gasteig concluding a festival to honour the 200th birthday of Franz Liszt on October 22. The program Hommage à Liszt juxtaposed chamber music by Liszt with that by Graham Waterhouse. The music was scored for piano solo up to piano and string quartet, including the premiere of Rhapsodie Macabre.
 Passage 2:Beechey began racing at the age of 22 in a Ford Customline V8. He came to prominence only a year later when he won the Olympic Touring Car Race at Albert Park, a support event at the Australian Grand Prix meeting which was held in conjunction with the 1956 Melbourne Olympic Games. As the expense of running this and two subsequent Customline V8s proved too prohibitive he reverted to a Holden 48-215 in 1959. After becoming part of David McKay’s Scuderia Veloce team he again returned to V8s, developing a Chevrolet Impala with which he won the New South Wales Touring Car Championship at Catalina Park. He progressed to a Ford Galaxie owned by Len Lukey and was then instrumental in forming the Neptune Racing Team in 1964. He raced a Holden EH S4 as part of that team alongside Jim McKeown’s Lotus Cortina and Peter Manton’s Morris Cooper S. He subsequently developed and raced a series of V8 powered Touring Cars with which he contested the Australian Touring Car Championship and other events. The first Ford Mustang to race in Australia was followed by a Chevrolet Chevy II Nova, a Chevrolet Camaro, a Holden Monaro GTS 327 and a Holden Monaro GTS 350.
 Passage 3:Ray Arnott played in a number of major Australian groups: he replaced founding drummer Mark Kennedy in Spectrum and played with them from 1971 until the group disbanded in 1973; this was followed by a brief stint in the short-lived "supergroup" Mighty Kong (which included former Cam-Pact/Co. Caine guitarist Russell Smith and former Daddy Cool members Ross Wilson and Ross Hannaford. This was followed by stints with The Dingoes (1973–1976), various solo projects (1978–80), Cold Chisel (1983–84) and Jimmy Barnes Band (1984–85). In 1969, Glass scored the role of Berger in the original Australian stage production of Hair, and performed on the award-winning original cast recording. After leaving that production, in the early 1970s (with David Pepperell he founded the pioneering Melbourne import record store "Archie & Jughead". In 1977 Glass established a new store and record label, Missing Link, which re-issued Cam-Pact material including a compilation album, Psychedelic Pop 'n' Soul 1967-69 (October 2002) alongside many other notable releases, including the earliest recordings by The Go-Betweens and The Birthday Party. Chris Löfvén became a film maker, creating pioneering Australian "film clips" (music videos) for Daddy Cool and Spectrum; he also directed a feature film, Oz (1976), alongside his continuing music work (often with Keith Glass). Russell Smith co-founded progressive rockers Company Caine (1970–75) and was also (with Arnott) a member of the short-lived Mighty Kong. Stockley was a founding member of early Australian "supergroup" Axiom (1969–71) and The Dingoes (1973–1978, 2009–present). Robert Lloyd went on to study and teach music and become a successful composer, poet, songwriter and recording artist.
