Chico piano scene is from A Night at the Opera, a 1935 American comedy film starring the Marx Brothers. It was the first of five films the Marx Brothers made under contract for MGM after their departure from Paramount Pictures, and the first after Zeppo left the act.
From the movie “The Big Store”, Chico and Harpo play in piano duet “Mamãe Eu Quero” (Mom, I want it), a very famous Brazilian song composed in 1937 by Vicente Paiva and Jararaca.
