Sullivan - I am the Very Model of a Modern Major-General (Pirates of Penzance)
"I Am the Very Model of a Modern Major-General" (often referred to as the "Major-General's Song" or "Modern Major-General's Song") is a patter song from Gilbert and Sullivan's 1879 comic opera The Pirates of Penzance. It is sung by Major-General Stanley at his first entrance, towards the end of Act I. The song satirises the idea of the "modern" educated British Army officer of the latter 19th century. It is one of the most difficult patter songs to perform, due to the fast pace and tongue-twisting nature of the lyrics.
Sullivan - Three Little Maids (from the Mikado)
"The Mikado", a comic opera in two acts, was the ninth operatic collaboration between librettist W.S. Gilbert and composer Arthur Sullivan. It is one of the most popular music theatre works written, running for 672 performances from its opening in 1885 at the Savoy Theatre and widely performed to this day. Perhaps the most beloved number in the work is the first act comic trio "Three Little Maids," ironic given that it was nearly cut from the original production, the cast successfully begging for it to be reinstated.
