Question: Who distributed Tonka and The Many Adventures of Winnie the Pooh? 
Context: "Winnie the Pooh" is the title song for the franchise of the same name.  It is musically emblematic of the most successful branding Disney currently owns and has been used in most merchandising models of the brand since the song's first publication in 1966 in the musical film featurette "Winnie the Pooh and the Honey Tree".  In film, the song is generally utilized in the title sequence.  The lyric gives an overview of the characters and the roles each plays in relation to Pooh himself.  The song has been used in every theatrically released Pooh film as well as most of the television series.  The songwriters are the Sherman Brothers, who have written the grand majority of Winnie the Pooh songs and musical numbers since 1966.  It is unknown who performed the song.  The song was also performed by Carly Simon.  A music video was released for this version and it was included in "The Many Adventures of Winnie the Pooh" DVD. Winnie the Pooh: A Valentine for You is a Valentine's Day special based on the Disney television series "The New Adventures of Winnie the Pooh" as well as A. A. Milne's treasured stories, originally broadcast on February 13, 1999.  This is the final role of Paul Winchell as Tigger (besides his performance as Tigger for the Many Adventures of Winnie the Pooh attraction at Walt Disney World Resort) before his retirement from the role in the same year and his death six years later.  It was released on VHS in 2000 and 2001 also released on DVD in 2004 and 2010. "Little Black Rain Cloud" is a song from the 1966 musical film featurette "Winnie the Pooh and the Honey Tree".  An instrumental version is played in the next featurette "Winnie the Pooh and the Blustery Day".  The song was also subsequently incorporated into the 1977 musical film, "The Many Adventures of Winnie the Pooh" which is an amalgamation of the three previous Winnie-the-Pooh featurettes including "Honey Tree".  In the song Winnie the Pooh comments about the on-screen actions where he is pretending to be a "Little Black Rain Cloud", as the title implies.  It's Pooh's hope that the Honey Bees will not notice him as he approaches their coveted honey. "Up, Down and Touch the Ground" is a song from the 1966 musical film featurette "Winnie the Pooh and the Honey Tree".  The song was also subsequently incorporated into the 1977 musical film, "The Many Adventures of Winnie the Pooh" which is an amalgamation of the three previous Winnie-the-Pooh featurettes including "The Honey Tree".  In the song Winnie the Pooh's exercise makes him hungry, and although he over-eats (it leads to his stuck-in-Rabbit's door incident later in the film), he is proud of his fat stomach and he exercises to gain weight and grow even rounder.  Halfway through the song however, he bends down too far, accidentally ripping the stitching on his bottom as a result of becoming fat, but upon seeing his bottom in the mirror, he quickly ties it together again.  By the end of the song Pooh has rationalized his over-eating by calling his hunger, "healthy".

The song was written by the Sherman Brothers who have written most of the music for the Winnie-the-Pooh franchise over the many years.  It was sung by an unidentified off-screen chorus with occasional lines sung by veteran character actor Sterling Holloway who provided the voice of Pooh. Winnie the Pooh and the Blustery Day is a 1968 animated featurette based on the third, fifth, ninth, and tenth chapters from "Winnie-the-Pooh" and the second, eighth, and ninth chapters from "The House at Pooh Corner" by A. A. Milne.  The featurette was produced by Walt Disney Productions and released by Buena Vista Distribution Company on December 20, 1968 as a double feature with "The Horse in the Gray Flannel Suit".

"The Wonderful Thing About Tiggers" is the theme song and personal anthem of Tigger, a fictional tiger from the children's book series Winnie-the-Pooh.  Although Tigger's birthday is believed to be in October 1928, the year that "The House at Pooh Corner" was first published, on Tigger-related merchandise, Disney often indicates Tigger's birth year as 1968, a reference to the first year that Tigger appeared in a Disney production, "Winnie the Pooh and the Blustery Day".  That was also the same instance when Tigger first sang this song.  The song is repeated in Disney's 1974 release "Winnie the Pooh and Tigger Too! ", The Many Adventures of Winnie the Pooh ride and then again in the 1977 release "The Many Adventures of Winnie the Pooh".
