Question: What golf course did Romero win his first senior title? Passage:Romero first played on the European Tour in 1985 and was a full member from 1988 to 2005. He has 8 tournament victories and seven top twenty placings on the Order of Merit. In 2002 he became the third oldest winner on the European Tour (behind Des Smyth and Neil Coles) when he won the Scottish Open just three days before his 48th birthday. Romero came fifth on the Order of Merit for 2002. Romero turned fifty in 2004, and just a few days later he finished in a tie for second at his first senior tournament, the Senior British Open. In 2005 he won his first senior title at the European Seniors Tour's Travis Perkins Senior Masters, and he won the Wentworth Senior Masters in both 2005 and 2006. In 2006, he lost in a playoff against Loren Roberts for the Senior British Open Championship and won a playoff against Lonnie Nielsen for the JELD-WEN Tradition for his first Champions Tour win and major. He was the Champions Tour's 2006 Rookie of the Year. He won the U.S. Senior Open, his second major, at The Broadmoor in Colorado Springs in 2008.

Question: Who are the members of the group who collaborated with other singers multiple times for Bob Wills is Still the King? Passage:And in any case, people in Texas came to identify with the song. The work of the Austin-based group Asleep at the Wheel helped to keep popular knowledge of Wills going, and they collaborated with Clint Black on a new version of "Bob Wills Is Still the King" on a 1999 tribute album Ride With Bob. Another recording of the song by Asleep at the Wheel, this time in collaboration with Waylon's son Shooter Jennings together with Randy Rogers and Reckless Kelly, appeared on the 2015 effort . The song itself is collected on several Jennings live sets, compilations, and box sets, including RCA Country Legends (2001 compilation, includes studio version),  Live from Austin, TX (recorded 1989, released 2006), and Nashville Rebel (2006 box set including studio version). Perhaps the most unexpected appearance was a performance by The Rolling Stones in Austin in 2006 during their A Bigger Bang Tour. Their arrangement featuring Ronnie Wood playing pedal steel guitar was captured on their 2007 The Biggest Bang concert DVD release.

Question: Which of the stop-motion animated works created by Firmin and Postgate had the most success? Passage:The popularisation of television broadcasting in the UK during the 1950s brought with it both new avenues for animation production and a shift in the demographic orientation of animation to the realms of children's programming. The year 1950 saw the premier of the long-running children's TV series Watch with Mother (1950–74) which would not include animation per se, but would feature several puppet-based segments (such as "Andy Pandy" and "Flower Pot Men") that would later become staples of British children's popular imagery and animation. Such is the case as well with the children's book character Noddy, who has appeared in various iterations and with different means of animation ranging from stop-motion to CGI to this day. The BBC's investment in resources and personnel oriented to children's media during this time would also provide avenues for the service's eventual inclusion of animation—particularly stop-motion animation, which could be derived from some of the same resources and skill-sets as live action puppetry. Puppeteer Gordon Murray for example, would branch off from his work on the "Watch with Mother" segment "The Woodentops" and other live action puppet shows to create several stop motion animated children's series in the 1960s, including "Camberwick Green" (1966), "Trumpton" (1967) and "Chigley" (1969). Modelmaker Peter Firmin and writer Oliver Postgate similarly created several stop-motion animated works for children during this period, including "Pingwings" (1961–1964), "Pogles' Wood" (1966–1967) and "Clangers" (1969–1972). It is during this period that ties between the UK's children's animation and several other British media and literary tendencies consolidated, with shows of this period providing a blueprint for future children's TV focussing on rural communities and day-to-day interpersonal relationships. Within this tendency, strong ties can be seen within children's TV and much older pastoral children's literature, social realist cinema and documentary, and the theatrical comedy of manners. This transition from puppetry to stop-motion also demonstrates the influence of Eastern European animation (such as that of Czech animator Jiří Trnka and his followers), with its own proclivity for wood and felt animation puppets and often static facial features. Trnka's work helped to inspire British production companies, including Pete Bryden and Ed Cookson's BBC-commissioned stop-frame animated children's series Summerton Mill (2005).
