question:
Question: Which of the Beatles who used the Gibson J-160E were older when they died? Passage:Both John Lennon and George Harrison used the Gibson J-160E, an acoustic guitar with an electric pickup at the base of the fretboard. The resonant character of the full acoustic body, combined with the electric pickup, meant that this guitar was susceptible to feedback, employed to great effect on the intro to "I Feel Fine". Lennon also used a Framus Hootenanny twelve-string acoustic, which can be seen in the movie Help! and heard on the title song and "You've Got to Hide Your Love Away". This twelve-string guitar accounted for audibly richer rhythm guitar parts on songs like these, in comparison to the six-string Gibsons. After Sgt. Pepper's Lonely Hearts Club Band, Lennon moved on to a Martin D-28 from C. F. Martin & Company (alternating between the J-160E and the D-28 for The White Album) while Harrison upgraded to a Gibson J-200 Jumbo (which Lennon used on "Two of Us" and other acoustic tracks on Let It Be).

question:
Question: What was the name of Yes first two albums? Passage:Hot on the heels of the huge success of CSNY and Led Zeppelin, British band Yes rapidly established themselves as one of the leading groups in the burgeoning progressive rock genre, and their success also played a significant part in establishing the primacy of the long-playing album as the major sales format for rock music in the 1970s. After several lineup changes during 1969–70, the band settled into its "classic" incarnation, with guitarist Steve Howe and keyboard player Rick Wakeman, who both joined during 1971. Although the extended length of much of their material made it somewhat difficult to promote the band with single releases, their live prowess gained them an avid following and their albums were hugely successful – their third LP The Yes Album (1971), which featured the debut of new guitarist Steve Howe, became their first big hit, reaching #4 in the UK and just scraping onto the chart in the US at #40. From this point, and notwithstanding the impact of the punk/new wave movement in the late 1970s, the band enjoyed an extraordinary run of success—beginning with their fourth album Fragile, each of the eleven albums they released between 1971 and 1991 (including the lavishly packaged live triple-album Yessongs) made the Top 20 in the US and the UK, and the double-LP Tales of Topographic Oceans (1973) and Going For The One (1977) both reached #1 in the UK.

question:
Question: How long has Nakayama been president of Sega when he was looking for a flagship series to compete with Mario? Passage:In 1990, Sega president Hayao Nakayama sought a flagship series to compete with Nintendo's Mario franchise along with a character to serve as a company mascot. Several character designs were submitted as part of a contest. Among the designs was an egg-shaped man wearing pajamas who resembled Theodore Roosevelt, drawn by Naoto Ohshima. According to Ohshima, the resemblance to Roosevelt was unintentional, saying he was influenced by a variety of characters. Retrospective sources have indicated Ohshima based the character on Humpty Dumpty and Mario. The Roosevelt lookalike did not win the contest; rather, another Ohshima character, a hedgehog named Mr. Needlemouse—later renamed Sonic—prevailed. As development of the Sega Genesis game Sonic the Hedgehog progressed, however, programmer Yuji Naka and the rest of Sonic Team thought the rejected design was excellent and deserved inclusion in the game. Since the character could not be the protagonist, the team retooled him into the game's main antagonist.
