Background: Donald Christopher Barber (born 17 April 1930) is an English jazz musician, best known as a bandleader and trombonist. As well as scoring a UK top twenty trad jazz hit, he helped the careers of many musicians, notably the blues singer Ottilie Patterson, who was at one time his wife, and vocalist/banjoist Lonnie Donegan, whose appearances with Barber triggered the skiffle craze of the mid-1950s and who had his first transatlantic hit, "Rock Island Line", while with Chris Barber's band. His providing an audience for Donegan and, later, Alexis Korner makes Barber a significant figure in the British rhythm and blues and "beat boom" of the 1960s.
Context: Barber and Monty Sunshine (clarinet) formed a band in 1953, calling it Ken Colyer's Jazzmen to capitalise on their trumpeter's recent escapades in New Orleans: the group also included Donegan, Jim Bray (bass), Ron Bowden (drums) and Barber on trombone. The band played Dixieland jazz, and later ragtime, swing, blues and R&B. Pat Halcox took over on trumpet in 1954 when Colyer moved on after musical differences and the band became "The Chris Barber Band".  In April 1953 the band made its debut in Copenhagen, Denmark. There Chris Albertson recorded several sides for the new Danish Storyville label, including some featuring only Sunshine, Donegan and Barber on double bass. In 1959 the band's version of Sidney Bechet's "Petite Fleur", a clarinet solo by Monty Sunshine with Barber on string bass, spent twenty-four weeks in the UK Singles Charts, making it to No. 3 and selling over one million copies, and was awarded a gold disc. After 1959 he toured the United States many times (where "Petite Fleur" charted at #5).  In the late 1950s and early 1960s Barber was mainly responsible for arranging the first UK tours of blues artists Big Bill Broonzy, Sonny Terry and Brownie McGhee and Muddy Waters. This, with the encouragement of local enthusiasts such as Alexis Korner and John Mayall, sparked young musicians such as Peter Green, Eric Clapton and the Rolling Stones. British rhythm and blues powered the British invasion of the USA charts in the 1960s, yet Dixieland itself remained popular: in January 1963 the British music magazine, NME reported the biggest trad jazz event in Britain at Alexandra Palace. It included George Melly, Diz Disley, Acker Bilk, Alex Welsh, Kenny Ball, Ken Colyer, Sunshine, Bob Wallis, Bruce Turner, Mick Mulligan and Barber.  Barber stunned traditionalists in 1964 by introducing blues guitarist John Slaughter into the line up who, apart from a break between April 1978 and August 1986, when Roger Hill took over the spot, played in the band until shortly before his death in 2010. Barber next added a second clarinet/saxophone and this line-up continued until 1999. Then Barber added fellow trombonist/arranger Bob Hunt and another clarinet and trumpet. This eleven-man "Big Chris Barber Band" offered a broader range of music while reserving a spot in the programme for the traditional six-man New Orleans line-up.  A recording of the Lennon-McCartney composition "Catswalk" can be heard, retitled "Cat Call", on The Songs Lennon and McCartney Gave Away. Written by Paul McCartney the song was recorded in late July 1967 and released as a single in the UK on 20 October 1967.
Question: Was this band successful?
Answer: making it to No. 3 and selling over one million copies, and was awarded a gold disc.

Background: Thomson was born in Glasgow, Scotland, the youngest of six children. He arrived in the United States two years later. His father, a cabinet maker, had moved to New York City shortly before Bobby's birth and sent for his family in 1925. Thomson grew up on Staten Island in New York City and signed with the New York Giants for a $100 bonus right out of Curtis High School in 1942.
Context: Longstanding rumors that the Giants engaged in systematic sign stealing during the second half of the 1951 season were confirmed in 2001. Several players told the Wall Street Journal that beginning on July 20, the team used a telescope, manned by coach Herman Franks in the Giants clubhouse behind center field, to steal the finger signals of opposing catchers. Stolen signs were relayed to the Giants dugout via a buzzer wire. Joshua Prager, the author of the Journal article, outlined the evidence in greater detail in a 2008 book.  Although Thomson always insisted that he had no foreknowledge of Branca's pitch, Sal Yvars told Prager that he relayed Rube Walker's fastball sign to Thomson. Branca was privately skeptical of Thomson's denials but made no public comment at the time. Later he told The New York Times, "I didn't want to diminish a legendary moment in baseball. And even if Bobby knew what was coming, he had to hit it.... Knowing the pitch doesn't always help." Whether the telescope-and-buzzer system contributed significantly to the Giants' late-season 37-7 win streak remains a subject of debate. Prager notes in his book that sign stealing was not specifically forbidden by MLB rules at the time and, moral issues aside, "...has been a part of baseball since its inception". Sign stealing using optical or other mechanical aids was outlawed by MLB in 1961.  Thomson however, late in his life, rebuked his prior claims of not receiving the sign on the Shot Heard 'Round the World, and admitted that the sign was received.
