"Stars and Stripes Forever", composed by John Philip Sousa in 1986 (briefly featured in an over-the-top rendition by a toon brass band in the Acme warehouse)-
Hungarian Rhapsody No. 2, S.244/2, composed by Franz Liszt in 1847. If there was a "national anthem" for toons, this would be one of the contenders. It first appeared in animation in Disney's 1929 short The Opry House, performed by Mickey Mouse. It's best known for appearing the Warner Bros. shorts Rhapsody in Rivets (1941) and Rhapsody Rabbit (1946), and MGM's The Cat Concerto (the same year- no one's sure who plagiarized who). It's been adapted to lyrics as "Freddy Get Ready" (sung by Bugs Bunny, Doris Day and Jack Carson) in My Dream is Yours (1949) and "Daffy Duck's Rhapsody" (1950, sung by you-know-who).
"Why Don't You Do Right?", written by Kansas Joe McCoy in 1936 (originally titled "Weed Smoker's Dream (Why Don't You Do Now)")-
"The Merry-Go-Round Broke Down", written by Cliff Friend and Dave Franklin in 1937, best known as the theme tune of the Looney Tunes.
"Witchcraft", music by Cy Coleman, words by Carolyn Leigh, 1957 (exactly ten years after WFRR's 1947...)-
And finally, "Smile, Darn Ya, Smile!", words by Chas O'Flynn and Jack Meskill, music by Max Rich, 1931. Disney probably chose the song because of its appearance in the '31 Merrie Melodie of the same name below:
Here's a little digression on the cartoon above:
And, the song itself-
