John Alexander Brymer OBE was an English clarinettist and saxophonist. The Times called him "the leading clarinettist of his generation, perhaps of the century". He was largely self-taught as a player, and he performed as an amateur before being invited by Sir Thomas Beecham to join the Royal Philharmonic Orchestra in 1947. He remained with the orchestra until 1963, two years after Beecham's death.

Sir Thomas Beecham, 2nd Baronet, CH was an English conductor and impresario best known for his association with the London Philharmonic and the Royal Philharmonic orchestras. He was also closely associated with the Liverpool Philharmonic and Hallé orchestras. From the early 20th century until his death, Beecham was a major influence on the musical life of Britain and, according to the BBC, was Britain's first international conductor.
