Harpo Marx painted "his" portrait. In 1955, Harpo made an appearance on the sitcom "I Love Lucy," in which he and Lucille Ball re-enacted the famous mirror scene from the Marx Brothers movie "Duck Soup" (1933). In this scene, they are both supposed to be Harpo, not Groucho; he stays the same and she is dressed as him. About this time, he also appeared on NBC's "The Martha Raye Show". Harpo recorded an album of harp music for RCA Victor ("Harp by Harpo", 1952) and two for Mercury Records ("Harpo in Hi-Fi", 1957; "Harpo at Work", 1958). Harpo and Chico played a
Marx Brothers Cream" sketch. In a 1969 interview with Dick Cavett, Groucho said that the two movies made with Thalberg were the best that they ever produced. Despite the Thalberg films' success, the brothers left MGM in 1937; Thalberg had died suddenly on September 14, 1936, two weeks after filming began on "A Day at the Races", leaving the Marxes without an advocate at the studio. After a short experience at RKO ("Room Service", 1938), the Marx Brothers returned to MGM and made three more films: "At the Circus" (1939), "Go West" (1940) and "The Big Store" (1941).
