Richard Anthony "Dick" Charlesworth (8 January 1932 – 15 April 2008) was an English jazz clarinettist, saxophonist and bandleader.
Charlesworth was born and brought up in Sheffield and attended King Edward VII School. At 16, he became a clerk in the Ministry of Labour and was in due course transferred to London. He bought a clarinet and started playing jazz as a hobby in 1952-53. He was entirely self-taught, but became good enough to play clarinet and saxophone in a dance band and perform with jazz bands in south London including Jim Weller’s Jazzmen. He formed his first group in 1956 while still doing his day job, and his 'Dick Charlesworth's Jazzmen' won the South London Jazz Band Championship in 1957. Charlesworth's group was signed by the Melodisc label, and they recorded an EP in December 1957 and produced an album for Doug Dobell's 77 Records.
Charlesworth left the Civil Service in 1959 and became a professional musician. He signed a recording contract with EMI and his group was remarketed as 'Dick Charlesworth's City Gents'. This was the time when light jazz was popular in the British charts as typified by Acker Bilk and Kenny Ball, also attired in distinctive costumes. Charlesworth's group sported pin stripes and bowler hats, and had a Latin motto, Dum vivimus vivamus, (“While we live, let us enjoy life”). Their only chart single was "Billy Boy",which reached 41 in the UK Singles Chart in May 1961. The City Gents often appeared on television including The Morecambe and Wise Show and Sunday Night at the London Palladium. Charlesworth sang the title song of a comedy film, In the Doghouse, starring Leslie Phillips and featured in his own 15 minute musical short in 1963.
