The Sorceror and Cox & Box

The Sorcerer is a two-act comic opera, with a libretto by W. S. Gilbert and music by Arthur Sullivan. It was the British duo's third operatic collaboration. The plot of The Sorcerer is based on a Christmas story, An Elixir of Love, that Gilbert wrote for The Graphic magazine in 1876. A young man, Alexis, is obsessed with the idea of love levelling all ranks and social distinctions. To promote his beliefs, he invites the proprietor of J. W. Wells & Co., Family Sorcerers, to brew a love potion. This causes everyone in the village to fall in love with the first person they see and results in the pairing of comically mismatched couples. In the end, Wells must sacrifice his life to break the spell.

Cox and Box; or, The Long-Lost Brothers, is a one-act comic opera with a libretto by F. C. Burnand and music by Arthur Sullivan, based on the 1847 farce Box and Cox by John Maddison Morton. It was Sullivan's first successful comic opera. The story concerns a landlord who lets a room to two lodgers, one who works at night and one who works during the day. When one of them has the day off, they meet each other in the room and tempers flare. Sullivan wrote this piece five years before his first opera with W. S. Gilbert
