Input: Question: How many bands competed in the Union Grove Fiddler's Convention competition against John Herald and his band? Passage 1:On December 10, 1817, Mississippi became the 20th state admitted to the Union. By 1860, Mississippi was the nation's top cotton producing state and enslaved persons accounted for 55% of the state population. Mississippi declared its secession from the Union on March 23, 1861, and was one of the seven original Confederate States. Following the Civil War, it was restored to the Union on February 23, 1870. Until the Great Migration of the 1930s, African Americans were a majority of Mississippi's population. Mississippi was the site of many prominent events during the American Civil Rights movement, including the 1962 Ole Miss riots, the 1963 assassination of Medgar Evers, and the 1964 Freedom Summer murders. Mississippi frequently ranks low among states in measures of health, education, and development, and high in measures of poverty. In 2010, 37.3% of Mississippi's population was African American, the highest percentage for any state.
 Passage 2:In 1958, Herald formed The Greenbriar Boys, along with Bob Yellin (banjo) and Paul Prestopino (mandolin). The following year, Eric Weissberg (mandolin and fiddle), replaced Prestopino, and Weissberg was soon replaced by Ralph Rinzler (mandolin) to form their most successful combination. Herald was lead guitarist and vocalist. The trio often played the Greenwich Village scene, but were notable enough to be the first Northern group to win the likes of the Union Grove Fiddler's Convention competition, where Yellin also took top honors for banjo. Shortly after backing Joan Baez on her second LP, The Greenbriar Boys were signed to Vanguard Records, for whom they released three records. In 1969, Linda Ronstadt recorded Herald's "High Muddy Water." Two years previously, she had recreated his vocal of Mike Nesmith's "Different Drum," which became a hit for her band the Stone Poneys.
 Passage 3:U.S. Route 13 runs north-south through the eastern part of Camden, heading north toward Dover and south toward Salisbury. U.S. Route 13 Alternate passes north-south through the center of Camden on Main Street. Delaware Route 10 runs east-west through Camden on Camden-Wyoming Avenue, heading west through rural western Kent County to the Maryland border and east toward Dover Air Force Base. DART First State provides bus service to Camden along Route 104, which runs from the Walmart in Camden north to the Dover Transit Center in Dover and connects to other local bus routes serving the Dover area; Route 117, which runs from the Walmart in Camden south to Harrington; and Route 303, which heads north to Dover and south to Georgetown.
