Question: Did the group that Stinson founded have more than three members? Passage:Gregory E. Stinson, better known as G. E. Stinson (born in Kingfisher, Oklahoma), is an American guitarist and founding member of new age/electronic musical group Shadowfax. Inspired by blues masters such as Bo Diddley and Muddy Waters, Stinson experimented with blues, jazz and other musical genres before co-founding Shadowfax in 1974. He remained with the band for six albums. He departed Shadowfax after recording The Odd Get Even (1989), entering the Los Angeles underground music community to refine his 'extended technique' and 'frequency manipulation'. Since then he has worked with a number of musicians on various projects, including Napalm Quartet, Splinter Group, Stinkbug, Metalworkers, Alex De Grassi, Devin Sarno and others. In 2000, he collaborated with drummer Gregg Bendian, violinist Jeff Gauthier, and bassist Steuart Liebig on an album of collective improvisational pieces recorded live in the studio, entitled Bone Structure. Released in 2003, it was given four stars by Jim Andrews in DownBeat magazine.

Question: Who is the oldest band that Eric listens to? Passage:Eric is a well-known fan of science fiction, such as  and especially Star Wars, in which he compares himself to Luke Skywalker. He is also known to have a large, beloved collection of G.I. Joe. He listens to artists such as Led Zeppelin, KISS, Aerosmith, Pink Floyd, Lynyrd Skynyrd, Deep Purple, Queen, Styx and Rush. He is also a Beatles fan and has been known to liken his group of friends to them, accusing Jackie of "breaking up the band" with her romantic entanglements with Kelso and Hyde (calling her Yoko, in reference to Yoko Ono). It is also hinted that he is both a Batman and Spider-Man fan, having Spider-Man bed sheets and a considerable number of comic books, most of them bearing the Marvel Comics logo with the titular character on the covers. When he fights a fan at the Packers game, he tells Red that he learned his moves from Spider-Man; coincidentally, Topher Grace starred as Eddie Brock, a character who obtains powers very similar to Spider-Man, thus transforming him into the monstrous Venom in Spider-Man 3 in 2007.

Question: How old was the man who took when he took command of the Army of the Eastern Pyrenees in 1794? Passage:In the first dismal months of fighting, the Army of the Eastern Pyrenees was beaten at Mas Deu and Bellegarde and forced back under the walls of Perpignan. Then the French repelled two Spanish attacks at Perpignan and Peyrestortes. Though the army was defeated again at Truillas and in other actions, the Spanish invaders withdrew to the Tech River in late 1793. Throughout the year the representatives on mission had enormous powers and used them to interfere with the military effort and to arrest officers that they deemed unpatriotic or unsuccessful. In 1794, the army's fortunes improved when Jacques François Dugommier took command. The army drove the Spanish army from France soil at Boulou and recaptured the Fort de Bellegarde and Collioure. After establishing itself on Spanish territory, the army won a decisive victory at the Battle of the Black Mountain in November during which Dugommier was killed. His replacement, Dominique Catherine de Pérignon soon captured the Sant Ferran fortress and the port of Roses. After these events the front became static and the last notable action was a Spanish victory at Bascara in June.
