Problem: Background: Weather Report was an American jazz fusion band of the 1970s and early 1980s. The band was initially co-led by the Austrian-born keyboard player Joe Zawinul, the American saxophonist Wayne Shorter and Czech bassist Miroslav Vitous. Due to creative and financial disagreements, Vitous left the band after a few years. Zawinul took increasing control and steered the band towards a more funk, R&B oriented sound.
Context: Joe Zawinul and Wayne Shorter had first met and become friends in 1959 while they were playing in Maynard Ferguson's Big Band. Zawinul went on to play with Cannonball Adderley's group in the 1960s, while Shorter joined Art Blakey's Jazz Messengers and then, in 1964, Miles Davis' second great quintet. During this decade, both men made names for themselves as being among the best composers in jazz.  Zawinul later joined Shorter in contributing to the initial fusion music recordings of Miles Davis, and both men were part of the studio groups, which recorded the key Davis albums In a Silent Way (1969) and Bitches Brew (1970). In consequence, Weather Report has often been seen as a spin-off from the Miles Davis bands of the late 1960s and early 1970s, although Zawinul was never part of Davis's touring line-up. Weather Report was initially formed to explore a more impressionistic and individualistic music (or, as Zawinul put it, "away from all that eight bars shit and then you go to the bridge...")  Zawinul and Shorter recruited another Miles Davis associate, the classically trained Czech-born bass player Miroslav Vitous, who had previously played with Zawinul, as well as with Herbie Mann, Bob Brookmeyer, Stan Getz, and Chick Corea (Vitous has subsequently claimed that in fact Shorter and he had founded Weather Report, with Shorter bringing in Zawinul afterwards.) All three men composed, and formed the core of the project. To complete the band, the trio brought in former McCoy Tyner drummer Alphonse Mouzon and set about looking for a full-time auxiliary percussionist as they began to record their debut album. The initial recruits were session player Don Alias and symphony orchestra percussionist Barbara Burton. During recording, Alias quarreled with Zawinul (allegedly due to Zawinul being too dictatorial over the percussion approach) and the innovative Brazilian percussionist Airto Moreira (yet another Davis alumnus) was brought in to complete the record. John McLaughlin was also invited to join the group, but decided to pursue his solo career, instead.
Question: was this their first gig
Answer: 

Background: David was born on 28 January 1858, in St. Fagans near Cardiff, Wales, the eldest son of the Rev. William David, a fellow of Jesus College, Oxford, a classical scholar and naturalist and his wife Margaret Harriette (nee Thomson). His mother's cousin, William A. E. Ussher of the Geological Survey, first interested David in what was to be his life work. At the age of 12, David went to Magdalen College School, Oxford in 1870. In 1876 he gained a classical scholarship to New College, Oxford.
Context: When World War I broke out in 1914, David was a strenuous supporter of the war effort, supporting the campaign for conscription. In August 1915, after reading reports about mining operations and tunnelling during the Gallipoli Campaign, along with Professor Ernest Skeats, a professor at the University of Melbourne, David wrote a proposal to Senator George Pearce, the Australian Defence Minister, suggesting that the government raise a military force to undertake mining and tunnelling. After the proposal was accepted, David used his advocacy and organisational abilities to set up the Australian Mining Corps, and on 25 October 1915 he was appointed as a major, at the age of 57.  The first contingent of the corps consisted of 1,300 officers and men that were initially organised into two battalions before being reorganised into three tunnelling companies, as well as an electrical and mechanical mining company. After departing Australia for the United Kingdom in February 1916, the corps arrived on the Western Front in May 1916. Given the title 'Geological Adviser to the Controllers of Mines in the First, Second and Third Armies', David became relatively independent and spent his time in geological investigations, using his expertise to advise on the construction of dugouts, trenches, and tunnels, the siting of wells for provision of pure drinking water from underground supplies, giving lectures, and producing maps. In September 1916 he fell to the bottom of a well he was examining, breaking two ribs and rupturing his urethra. He was invalided to London but returned to the Front in November, assuming the role of geological technical advisor to the British Expeditionary Force.  On 7 June 1917 his wartime contribution culminated in the mining of German positions in the Battle of Messines. In January 1918, David was awarded the Distinguished Service Order and in November he was promoted to lieutenant colonel. The war having concluded, he was demobilised in 1919. He was also Mentioned in Despatches twice.
