Task: Question Answering
Input (English): Passage: Poulenc made his début as a composer in 1917 with his Rapsodie nègre, a ten-minute, five-movement piece for baritone and chamber group; it was dedicated to Satie and premiered at one of a series of concerts of new music run by the singer Jane Bathori. There was a fashion for African arts in Paris at the time, and Poulenc was delighted to run across some published verses purportedly Liberian, but full of Parisian boulevard slang. He used one of the poems in two sections of the rhapsody. The baritone engaged for the first performance lost his nerve on the platform, and the composer, though no singer, jumped in. This jeu d'esprit was the first of many examples of what Anglophone critics came to call "leg-Poulenc". Ravel was amused by the piece and commented on Poulenc's ability to invent his own folklore. Stravinsky was impressed enough to use his influence to secure Poulenc a contract with a publisher, a kindness that Poulenc never forgot.
In completely arbitrary fashion Collet chose the names of six composers, Auric, Durey, Honegger, Poulenc, Tailleferre and myself, for no other reason than that we knew each other, that we were friends and were represented in the same programmes, but without the slightest concern for our different attitudes and our different natures. Auric and Poulenc followed the ideas of Cocteau, Honegger was a product of German Romanticism and my leanings were towards a Mediterranean lyrical art ... Collet's article made such a wide impression that the Groupe des Six had come into being.
Cocteau, though similar in age to Les Six, was something of a father-figure to the group. His literary style, "paradoxical and lapidary" in Hell's phrase, was anti-romantic, concise and irreverent. It greatly appealed to Poulenc, who made his first setting of Cocteau's words in 1919 and his last in 1961. When members of Les Six collaborated with each other, they contributed their own individual sections to the joint work. Their 1920 piano suite L'Album des Six consists of six separate and unrelated pieces. Their 1921 ballet Les mariés de la tour Eiffel contains three sections by Milhaud, two apiece by Auric, Poulenc and Tailleferre, one by Honegger and none by Durey, who was already distancing himself from the group.In the early 1920s Poulenc remained concerned at his lack of formal musical training. Satie was suspicious of music colleges, but Ravel advised Poulenc to take composition lessons; Milhaud suggested the composer and teacher Charles Koechlin. Poulenc worked with him intermittently from 1921 to 1925. 
Question: What is the name of the person whose last setting of Cocteau's words was in 1961?
