\"The Man Who Broke the Bank at Monte Carlo\" is a popular British music hall song of the 19th century, written in 1891 or 1892 by Fred Gilbert (Frederick Younge Gilbert, 1850 - 1903), a theatrical agent who had begun to write comic songs as a sideline some twenty years previously.
The song was popularised by singer and comedian Charles Coborn, and quickly became a staple of his act, performed on tour in different languages throughout the world. Coborn confirmed that Gilbert's inspiration was the gambler and confidence trickster Charles Wells. Wells was reported to have won one-and-a-half million francs at the Monte Carlo casino, using the profits from previous fraud.
I personally found Coburn's version a bit fast and indistinct, so have done my interpretation at a slightly slower tempo.
