Rodolfo. One of the most recent is the 2008 Deutsche Grammophon release conducted by Bertrand de Billy with Anna Netrebko and Rolando Villazón as Mimì and Rodolfo. There are several recordings with conductors closely associated with Puccini. In the 1946 RCA Victor recording, Arturo Toscanini, who conducted the world premiere of the opera, conducts the NBC Symphony Orchestra with Jan Peerce as Rodolfo and Licia Albanese as Mimì. It is the only recording of a Puccini opera by its original conductor. Thomas Beecham, who worked closely with Puccini when preparing a 1920 production of La bohème in London, conducted a performance of the opera in English released by Columbia Records in 1936 with Lisa Perli as Mimì and Heddle Nash as Rodolfo. Beecham also conducts on the 1956 RCA Victor recording with Victoria de los Ángeles and Jussi Björling as Mimì and Rodolfo. Although the vast majority of recordings are in the original Italian, the opera has been recorded in several other languages. These include: a recording in French conducted by Erasmo Ghiglia with Renée Doria and Alain Vanzo as Mimì and Rodolfo (1960); a recording in German with Richard Kraus conducting the Deutsche Oper Berlin Orchestra and Chorus with Trude Eipperle and Fritz Wunderlich as Mimì and Rodolfo (1956); and the 1998 release on the Chandos Opera in English label with David Parry conducting the Philharmonia Orchestra and Cynthia Haymon and Dennis O'Neill as Mimì and Rodolfo. Enrico Caruso, who was closely associated with the role of Rodolfo, recorded the famous aria "Che gelida manina" in 1906. This aria has been recorded by nearly 500 tenors in at least seven different languages between 1900 and 1980. In 1981 the A.N.N.A. Record Company released a six LP set with 101 different tenors singing the aria. The missing act In 1957 Illica's widow died and his papers were given to the Parma Museum. Among them was the full libretto to La bohème. It was discovered that the librettists had prepared an act which Puccini decided not to use in his composition. It is noteworthy for explaining Rodolfo's jealous remarks to Marcello in act 3. The "missing act" is located in the timeline between the Café Momus scene and act 3 and describes an open-air party at Musetta's dwelling. Her protector has refused to pay further rent out of jealous feelings, and Musetta's furniture is moved into the courtyard to be auctioned
