Question: Gianni Schicchi included the aria set to a libretto by whom?
Context: Giuseppe De Luca (25 December 1876 – 26 August 1950), was an Italian baritone who achieved his greatest triumphs at the Metropolitan Opera in New York City.  He notably created roles in the world premieres of two operas by Giacomo Puccini: Sharpless in "Madama Butterfly" (at La Scala, Milan, 1904) and the title role in "Gianni Schicchi" (Metropolitan Opera, 1918). Jon Garrison (né Jon Long; born December 11, 1944 in Higginsville, Missouri) is a successful American operatic tenor who has been performing in locations around the world since 1965.  He first appeared at the Metropolitan Opera in 1974, in a secondary role in the company premiere of "Death in Venice", which featured Sir Peter Pears.  At that theatre, he has since been seen in "Gianni Schicchi" (as Rinuccio, 1975), "Don Pasquale" (as Ernesto, directed by John Dexter, 1979), "Fidelio" (as Jaquino, with Jon Vickers as Florestan, 1980), "Wozzeck" (as Andres, opposite Anja Silja, 1980), "Don Giovanni" (as Don Ottavio, 1994), "Die Fledermaus" (as Alfred, 1995), etc. Gianni Schicchi (] ) is a comic opera in one act by Giacomo Puccini to an Italian libretto by Giovacchino Forzano, composed in 1917–18.  The libretto is based on an incident mentioned in Dante's "Divine Comedy".  The work is the third and final part of Puccini's "Il trittico" (The Triptych)—three one-act operas with contrasting themes, originally written to be presented together.  Although it continues to be performed with one or both of the other "trittico" operas, "Gianni Schicchi" is now more frequently staged either alone or with short operas by other composers.  The aria "O mio babbino caro" is one of Puccini's best known, and one of the most popular arias in opera. "O mio babbino caro " ("Oh My Beloved Father") is a soprano aria from the opera "Gianni Schicchi" (1918) by Giacomo Puccini to a libretto by Giovacchino Forzano.  It is sung by Lauretta after tensions between her father Schicchi and the family of Rinuccio, the boy she loves, have reached a breaking point that threatens to separate her from Rinuccio.  It provides an interlude expressing lyrical simplicity and single-hearted love in contrast with the atmosphere of hypocrisy, jealousy, double-dealing, and feuding in the medieval Florence of Puccini's only comedy.  It provides the only set-piece in the through-composed opera. Jānis Liepiņš (born August 7, 1988 in Riga, Latvia) is a Latvian conductor.

Gianni Schicchi, Eugene Onegin, Romeo and Juliet, Scheherezade and Her Tales and La Bayadere; he was the conductor and musical director for the ballet Raymonda and operetta Die Fledermaus. This is a list of the recordings of Gianni Schicchi, the third of a group of three one-act operas by Giacomo Puccini collectively known as "Il trittico"; the other operas are "Il tabarro" and "Suor Angelica".  The three were premiered at the Metropolitan Opera on 14 December 1918, and for the next three years were always played together.  After 1921, however, Puccini agreed that the operas could be performed separately. " Gianni Schicchi" became the most popular and most frequently performed of the three, often paired with other works such as Maurice Ravel's "L'heure espagnole" and Richard Strauss's "Salome". Giovacchino Forzano (] ; 19 November 1884 – 28 October 1970) was an Italian playwright, librettist, stage director, and film director.  A resourceful writer, he authored numerous popular plays and produced opera librettos for most of the major Italian composers of the early twentieth century, including the librettos for Giacomo Puccini's "Suor Angelica" and "Gianni Schicchi".

In 2015, he made his most recent debuts as Macbeth at the Berliner Staatsoper, Don Carlo in "Ernani" at the Metropolitan Opera, and Gianni Schicchi at the Los Angeles Opera.
