Problem: Brown was born on July 28, 1891, in Holgate, Ohio, near Toledo, into a large family largely of Welsh descent. He spent most of his childhood in Toledo. In 1902, at the age of ten, he joined a troupe of circus tumblers known as the Five Marvelous Ashtons, who toured the country on both the circus and vaudeville circuits. Later he became a professional baseball player.

In 1939, Brown testified before the House Immigration Committee in support of a bill that would allow 20,000 German Jewish refugee children into the US. He later adopted two refugee children. During WWII, he spent a great deal of time entertaining troops, spending many nights working and meeting servicemen at the Hollywood Canteen. He wrote of his experiences entertaining the troops in his book Your Kids and Mine. Joe E. Brown's other two sons were in the military service. In 1942 Brown's son, Captain Don E. Brown, was killed when his A-20 Havoc crashed near Palm Springs, California. At 50, Brown himself was too old to enlist, but he traveled thousands of miles at his own expense to entertain American troops. He was the first to do so, traveling to both the Caribbean and Alaska before Bob Hope had, and before the USO was organized. "While big USO names like Bob Hope did not visit the Leyte, Philippine area my father was in (housing was not good), Leyte received any number of entertainers during the war. Dad said the entertainers were all just a bunch of nice people. One group in particular was the top actors from a very popular and large musical of the times. Dad and a few of his buddies would walk back to the tents that housed the USO performers and would visit with them. Mostly, the USO performers were curious about the events on the islands and how the men were handling things. One performer, a "wonderful comedian" named Joe E. Brown, would commandeer a military vehicle and be driven around the island. The entertainer would stop military pedestrians, "ream" them for some inconsequential matter, start laughing, then invite them into the cab so they could be driven to their destinations. Joe E. Brown was greatly appreciated." (Memories of Capt. Donald Courtright, told to his daughter Mary in 2011.) On his return to the States, he brought sacks of letters, making sure they were delivered by the Post Office Department. He gave shows in all weather conditions, many in hospitals, sometimes doing his entire show for a single dying soldier. He would sign autographs for everyone. Brown was one of only two civilians to be awarded the Bronze Star in WWII.

Question:
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.
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.
