Which of these Disney productions was released earlier--The Three Caballeros or The Monkey's Uncle?  
The Three Caballeros
The Three Caballeros
The Three Caballeros is a 1944 American live-action animated musical package film produced by Walt Disney and released by RKO Radio Pictures.
 The film premiered in Mexico City on December 21, 1944.
 It was released in the United States on February 3, 1945 and in the UK that March.
 The seventh Disney animated feature film, the film plots an adventure through parts of Latin America, combining live-action and animation.
 This is the second of the six package films released by Walt Disney Productions in the 1940s, following "Saludos Amigos" (1942).
The Monkey's Uncle
The Monkey's Uncle is a 1965 Walt Disney production starring Tommy Kirk as genius college student Merlin Jones and Annette Funicello (Who was a member of the mouseketeers from The Mickey Mouse Club) as his girlfriend, Jennifer.
 The title plays on the idiom "monkey's uncle" and refers to a chimpanzee named Stanley, Merlin's legal "nephew" (a legal arrangement resulting from an experiment to raise Stanley as a human); Stanley otherwise has little relevance to the plot.
 Jones invents a man-powered airplane and a sleep-learning system.
 The film is a sequel to the 1964 film "The Misadventures of Merlin Jones."
Panchito Pistoles
Panchito Pistoles is a cartoon character drawn as an anthropomorphized rooster.
 He appeared in the film "The Three Caballeros".
 Later he appeared in several Disney comics, including Don Rosa's "The Three Caballeros Ride Again" and "The Magnificent Seven (Minus 4) Caballeros".
 Panchito was the only one of the Three Caballeros to never appear in "Saludos Amigos", as he did not yet exist when the 1942 film was released before he first appeared in the 1944 film. Manuel Esperón
Manuel Esperón González (August 3, 1911 – February 13, 2011) was a Mexican songwriter and composer.
 He wrote many songs for Mexican films, including "¡Ay, Jalisco, no te rajes!
" for the 1941 film of the same name, "Cocula" for "El Peñón de las Ánimas" ("The Rock of Souls") (1943), and "Amor con amor se paga" for "Hay un niño en su futuro" (1952).
 Other Esperón compositions have become Latin standards such as "Yo soy mexicano", "Noche plateada" and "No volveré", which was used in the first episode of the 2001 soap opera "El juego de la vida".
 Among other performers, Chavela Vargas, Pedro Infante, Los Panchos, and Jorge Negrete have made his songs well-known.
 His fame in the USA derives from when his song "The Three Caballeros" was used in the Disney film "The Three Caballeros" (1944). Gran Fiesta Tour Starring The Three Caballeros
Gran Fiesta Tour Starring The Three Caballeros is a musical dark boat ride housed within the pyramid-shaped Mexico Pavilion, at the Epcot theme park at the Walt Disney World Resort in Florida.
 It was the first World Showcase attraction to feature Disney characters based on an existing property.
 Norway followed suit in 2014 when it closed its Maelstrom ride to make room for Frozen Ever After, which opened in 2016. Saludos Amigos
Saludos Amigos (Spanish for "Greetings, Friends") is a 1942 American live-action animated package film produced by Walt Disney and released by RKO Radio Pictures.
 It is the sixth Disney animated feature film and the first of the six package films produced by Walt Disney Productions in the 1940s.
 Set in Latin America, it is made up of four different segments; Donald Duck stars in two of them and Goofy stars in one.
 It also features the first appearance of José Carioca, the Brazilian cigar-smoking parrot.
 "Saludos Amigos" was popular enough that Walt Disney decided to make another film about Latin America, "The Three Caballeros", to be produced two years later.
 "Saludos Amigos" premiered in Rio de Janeiro on August 24, 1942.
 It was released in the United States on February 6, 1943.
 At 42 minutes, it is Disney's shortest animated feature to date.
 It garnered positive reviews and was theatrically reissued in 1949, when it was shown on a double bill with the first reissue of "Dumbo". Melody Time
Melody Time (working title All in Fun) is a 1948 American live-action animated film and the 10th theatrically released animated feature produced by Walt Disney.
 It was released to theatres by RKO Radio Pictures on May 27, 1948.
 Made up of several sequences set to popular music and folk music, the film is, like "Make Mine Music" before it, the popular music version of "Fantasia" (an ambitious film that proved to be a commercial disappointment upon its original theatrical release).
 "Melody Time", while not meeting the artistic accomplishments of "Fantasia", was mildly successful.
 It is the fifth Disney package film following "Saludos Amigos", "The Three Caballeros", "Make Mine Music", and "Fun and Fancy Free". Yale Gracey
Yale Gracey (1910 – September 5, 1983) was a Disney Imagineer, writer, and layout artist for many Disney animated shorts, including classics such as "The Three Caballeros" and "Fantasia".
 Gracey joined the company in 1939 as a layout artist for "Pinocchio".
 He designed many of the special effects for the Pirates of the Caribbean and Haunted Mansion attractions at Disneyland.
 The Haunted Mansion character Master Gracey was named in homage to him.
 Gracey retired from the company on October 4, 1975. Walt &amp; El Grupo
Walt & El Grupo is a 2008 documentary film written and directed by Theodore Thomas.
 A presentation of Walt Disney Family Foundation Films, the film tells the story of Walt Disney's 1941 U.S. Government sponsored trip to South America where he and a group of artists gathered material which would be used to create two of Disney's animated feature films, "Saludos Amigos" and "The Three Caballeros". South of the Border with Disney
South of the Border with Disney is a 1942 Disney short documentary film.
 It was shot in the same occasion "Saludos Amigos" was, when Walt Disney and a group of eighteen artists, musicians and writers went to South America looking for inspirations for a movie.
 While "Saludos Amigos" is the result of this voyage, alternating animated shorts to the sequences from the travel that inspired them, "South of the Border with Disney" is more of a behind-the-scenes documentary showing only the travel and the genesis of cartoons not only for "Saludos Amigos" and "The Three Caballeros", but also some others used in later occasions.
 The most notable example is a female Armadillo used for a 1943 Pluto cartoon, "Pluto and the Armadillo".
 Film also includes some pencil test animation.
