This chapter discusses Richard D'Oyly Carte's “Gilbert and Sullivan” (G & S) program, which was named after W. S. Gilbert and Arthur Sullivan. Carte's G & S program combined the appeal of superb craftsmanship with that of fresh material, replacing the previous derivative nature of extravaganza and burlesque. First of all, Carte commissioned Trial By Jury, G & S's only one-act production. It was a miniature comic opera. This led to the famous series of shows, now all with spoken dialogue, that changed the course of the Anglophone musical. However, by his involvement with Gilbert and Sullivan Carte had tasked himself weightily, as he now faced years of delicate diplomacy, keeping the act together when Gilbert got too prickly or Sullivan felt unappreciated. Next, Carte recruited G & S performers into the D'Oyly Carte Opera Company. The aim was to tour internationally in the G & S canon and this tradition lasted for over one hundred years. The business became a family business. After Carte retired the business was managed by his son Rupert, and then by Rupert's daughter Bridget, before disbanding in 1982, albeit with sporadic initiatives thereafter. The chapter finally looks into more detail at the G & S canon, including titles such as The Pirates Of Penzance (1879) and Patience (1881).
