Charles Green's twentieth Century Faydetts start out this little 4 minute reel with Because My Baby Don't Mean Maybe followed by a mash of several songs at :43. For the final number, the Faydetts play Changes at 1:36 to the end. A trio sings a few words to Changes:
Beautiful changes in different keys
Beautiful changes and harmonies
He starts in C then changes to D
He foolin' around, most any old key
What's that? Her that minor strain
There's so many babies that he can squeeze
And he's alway changing the keys.
If the lyrics are difficult to follow, its probably because the trio is singing a bit of scat in between the lines. Although the leader can definitely be identified as Nina Grey, none of the individual Faydetts are known.
Charles Green's Twentieth Century Faydetts, with Nina Grey. Vitaphone 710 filmed in Brooklyn, New York released March 20, 1929. 200 meter reel, mono Vitaphone sound, 7 minutes unedited. The missing 3 minutes are Victor Herbert's \"Ah Sweet Mystery of Life\" which was slow and mostly boring and was edited out of the film.

I couldn't identify the songs in the mashed up arrangement from :43 to 1:34.
