Premise: "Big Spender" is a song written by Cy Coleman and Dorothy Fields for the musical "Sweet Charity", first performed in 1966. It is sung, in the musical, by the dance hostess girls; it was choreographed by Bob Fosse for the Broadway musical and the film. It is set to the beat of a striptease as the girls taunt the customers.
Hypothesis: Big Spender was written in the 20th century.
