In its original format, the film contained 1249 feet of 2-strip Technicolor footage which, unfortunately, is either lost or unavailable at the present time; this unhappily includes the "Everybody Tap" number with Bessie Love and Charlie King at the beginning of Reel #5, "Love Ain't Nothin' But the Blues" with Charles King in blackface, a reprise of "My Dynamic Personality" by Marie Dressler and the "Happy Days Are Here Again" finale in Reel #11.
In the story, which was filmed in mid-1929, before the stock market crash, the song "Happy Days Are Here Again" is used as a celebration of the end of World War l, in November 1918, but in the 1930s it became such a depression themed anthem, its roots & original purpose were forgotten.
Though this is an MGM film, Bessie Love is seen reading an edition of Variety. On the back, blazoned in large letters are an advert for Universal's "King of Jazz"(1930).
As shown on TCM, the film ends abruptly with no warning that it's over when Carlie pushes Terry out of the dressing room door. This is the result of the loss of the 2-strip Technicolor finale which ended the film.
The two Technicolor sequences in this film were shot between August 19 and 21, 1929, and utilized seventy extras. 16,035 feet of Technicolor footage was shot for 1,249 feet that comprise the sequences inserted into the final version of the film.
According to Loew's Weekly (21 December 1929), the film's title was originally going to be "Happy Days."
