Question: Who was the leader of the Royal Green Jackets in 1966? Passage 1:Davis won Emmys in 1990 for Beauty and the Beast and 1995 for SeaQuest DSV. He wrote scores mostly for television series up until 1995, in which he wrote a few of the cues for the animated Disney motion picture A Goofy Movie. He continued to score television series until the two then young directors, the Wachowskis, hired him to score their neo-noir film Bound. It was reasonably successful at the box office. Bound was the film which led Davis into becoming the composer for the entire Matrix trilogy. Subsequently, Davis has composed scores for films such as Jurassic Park III (recommended to the filmmakers by John Williams, the composer of the scores for the first two films in the series), House on Haunted Hill, Behind Enemy Lines, and The Unsaid. In 2004, he produced the music score for the BBC science fiction documentary series Space Odyssey: Voyage to the Planets, released as Voyage to the Planets and Beyond in the United States.
 Passage 2:Roger Ebert of the Chicago Sun-Times gave the film three stars out of four and wrote that "the musical scenes are the best rock coverage since 'Woodstock.' The sound is first rate, for one thing, and director Pierre Adidge has some idea of why Cocker electrifies a crowd." Vincent Canby of The New York Times called the film a "most satisfying, record-album of a movie" which "patronizes neither its audience nor its stars ... It is uncluttered, one of the best concert films so far." A review in Variety said, "Considerable technical expertise has gone into this production, and though the objective may be clear, it just hasn't turned out to be another 'Woodstock,' possibly because Joe Cocker's personality isn't all that endearing." Gene Siskel of the Chicago Tribune rated the film three stars out of four and wrote, "'Mad Dogs' is distinguishable from other 'rockumentaries' because it deals almost exclusively with the musician and his music. There are few side trips to cultural comments." Robert Hilburn of the Los Angeles Times stated, "As a film, 'Mad Dogs and Englishmen' is a good concert. For much of the picture's 114 minutes, the camera is on Joe Cocker, by most standards the best and most exciting singer in rock music ... But 'Mad Dogs and Englishmen,' unfortunately, fails in the end to rise above this interesting, but clearly limited historical summary of the Cocker tour. As a film, it doesn't establish its own importance." A negative review by Tom Zito of The Washington Post advised readers to "Forget the film and try the record," explaining, "What emerges from all this is roughly two hours of footage that looks terrible on the screen and sounds almost as bad. The film is projected in an annoying square format, except for the moments when the screen area is broken up into some poorly coordinated split-screen effects. The camerawork is often sloppy ... the whole thing winds up looking and sounding like a cheap, imitation (indoor) 'Woodstock.'" James D. White of The Monthly Film Bulletin declared that "The music itself is excellent," but "The film's information content is minimal; and one's heart sinks as the screen is split into a double image for the first number and as the mandatory shots—of excited fans, of joint-rolling in a hotel bedroom, of an interview with a vacuous groupie—are inevitably wheeled out."
 Passage 3:The King's Royal Rifle Corps was an infantry rifle regiment of the British Army that was originally raised in British North America as the Royal American Regiment during the phase of the Seven Years' War in North America known as 'The French and Indian War.' Subsequently numbered the 60th Regiment of Foot, the regiment served for more than 200 years throughout the British Empire. In 1958, the regiment joined the Oxfordshire and Buckinghamshire Light Infantry and the Rifle Brigade in the Green Jackets Brigade and in 1966 the three regiments were formally amalgamated to become the Royal Green Jackets. The KRRC became the 2nd Battalion, Royal Green Jackets. On the disbandment of the 1st Battalion, Royal Green Jackets in 1992, the RGJ's KRRC battalion was redesignated as the 1st Battalion, Royal Green Jackets, eventually becoming 2nd Battalion, The Rifles in 2007.
