Question: Did "My Generation" or "Happy Jack" sell more copies by the year The Who performed at the Monterey Pop Festival? Passage 1:Walsh first developed what would become the West Coast offense when he was offensive coordinator of the Cincinnati Bengals, working under legendary head coach Paul Brown. However, Walsh truly perfected this strategy as the head coach of the San Francisco 49ers. His teams were led by quarterback Joe Montana. Montana, who was noted for his ability to remain calm under pressure, also possessed good mobility and an accurate passing arm. Another important player in the 49ers offense was Roger Craig, a swift, speedy running back who could also catch passes out of the backfield and was a good receiver. Walsh's 49ers teams also featured several All-Pro wide receivers, including Dwight Clark, John Taylor, and Jerry Rice. The 49ers were one of the NFL's powerhouses in the 1980s and 1990s, under the guidance of head coaches Bill Walsh (1979–1988) and George Seifert (1989–1996). Walsh won three Super Bowls in the 1981, 1984 and 1988 seasons. Seifert won two Super Bowls in 1989 and 1994. Montana, Walsh and Rice are in the Pro Football Hall of Fame, and so is Montana's successor, quarterback Steve Young. Like Montana, Young was a great running quarterback and a very efficient passer. 
 Passage 2:The Who developed from an earlier group, the Detours, and established themselves as part of the pop art and mod movements, featuring auto-destructive art by destroying guitars and drums on stage. Their first single as the Who, "I Can't Explain", reached the UK top ten, and was followed by a string of singles including "My Generation", "Substitute" and "Happy Jack". In 1967, they performed at the Monterey Pop Festival and released the US top ten single "I Can See for Miles", while touring extensively. The group's fourth album, 1969's rock opera Tommy, included the single "Pinball Wizard" and was a critical and commercial success. Live appearances at Woodstock and the Isle of Wight Festival, along with the live album Live at Leeds, cemented their reputation as a respected rock act. With their success came increased pressure on lead songwriter Townshend, and the follow-up to Tommy, Lifehouse, was abandoned. Songs from the project made up 1971's Who's Next, which included the hit "Won't Get Fooled Again". The group released the album Quadrophenia in 1973 as a celebration of their mod roots, and oversaw the film adaptation of Tommy in 1975. They continued to tour to large audiences before semi-retiring from live performances at the end of 1976. The release of Who Are You in 1978 was overshadowed by the death of Moon shortly after.
 Passage 3:On May 7 against the Detroit Tigers, Mark Buehrle pitched a no-hitter through seventh inning before Plácido Polanco hit a line-drive double to left field; however the Sox shut out the Tigers 6–0. On May 11 against the Cleveland Indians in Progressive Field, Carlos Quentin hit a slump after suffering from plantar fasciitis which hampered his swing. He was forced to miss two games as a result of the injury. On May 15–18, Sox played with Toronto Blue Jays and Sox lost all four games in Toronto for two straight years and lost 10 straight games in Toronto since June 1, 2007. On May 21 against the Minnesota Twins, the Sox had a biggest loss 20–1 since May 10, 2002, when Sox lost to Anaheim Angels 19–0 in Los Angeles. On May 24 against the Pittsburgh Pirates, in the top of the ninth inning, Jack Wilson hit his first home run of season and tied the game at 3. The next batter Nyjer Morgan hit a double and then Delwyn Young singled and Morgan scored from second and Sox trailed it 4–3. In the bottom of the ninth inning, all batters that Matt Capps faced struck out swinging. The next day in Los Angeles against the Angels, the Sox scored 17 runs in one game, the most runs since the 2006 season. Also on that day, Carlos Quentin suffered his heel injury after he hit a double and he was placed on the 15-day disabled list. The last three games of that month, Sox swept the Royals in Kansas City. The White Sox finished May 13–15.
