Document 9: The Bare Necessities: "The Bare Necessities" is a song, written by Terry Gilkyson, from the animated 1967 Disney film "The Jungle Book", sung by Phil Harris as Baloo and Bruce Reitherman as Mowgli. Originally, it was written for an earlier draft of the movie that was never produced. The Sherman Brothers, who wrote the other songs of the film, kept this as the only song used from the previous version. A reprise of the song was sung by Sebastian Cabot as Bagheera and Phil Harris as Baloo at the end of the film. Van Dyke Parks worked on the arrangement, which was his first paid gig after moving to California. The song was also sung by Louis Armstrong. In 1967, "The Bare Necessities" was nominated for an Academy Award for Best Original Song. A hip-hop version of the song performed by Lou Rawls was used as the theme song for "Jungle Cubs".

It was originally sung by Dick Van Dyke and Julie Andrews, and also is featured in the Cameron Mackintosh/Disney "Mary Poppins" musical.

Document 11: Frosty the Snowman: "Frosty the Snowman" (or "Frosty the Snow Man") is a popular Christmas song written by Walter "Jack" Rollins and Steve Nelson, and first recorded by Gene Autry and the Cass County Boys in 1950. It was written after the success of Autry's recording of "Rudolph the Red-Nosed Reindeer" the previous year; Rollins and Nelson shipped the new song to Autry, who recorded "Frosty" in search of another seasonal hit. Like "Rudolph", "Frosty" was subsequently adapted to other media including a popular television special by Rankin/Bass Productions (formerly known as Videocraft International), "Frosty the Snowman". The ancillary rights to the Frosty the Snowman character are owned by Warner Bros., but due to the prominence of the TV special, merchandising of the character is generally licensed in tandem with that special's current owners, DreamWorks Classics.
Document 12: I Love to Laugh: "I Love to Laugh", also called "We Love to Laugh", is a song from Walt Disney's film "Mary Poppins". It was composed by Richard M. Sherman and Robert B. Sherman. The song is sung in the film by "Uncle Albert" (Ed Wynn), and "Bert" (Dick Van Dyke) as they levitate uncontrollably toward the ceiling, eventually joined by Mary Poppins (Julie Andrews) herself. The premise of the scene, that laughter and happiness cause Uncle Albert (and like-minded visitors) to float into the air, can be seen as a metaphor for the way laughter can "lighten" a mood. (Compare Peter Pan's flight power, which is also powered by happy thoughts.) Conversely, thinking of something sad literally brings Albert and his visitors "down to earth" again. The song states a case strongly in favor of laughter, even if Mary Poppins appears to disapprove of Uncle Albert's behavior, especially since it not only complicates the task of getting Albert down, but the infectious mood sends Bert and the Banks children into the air as well.
