Despite the multitudes of references a search brought up, I’m having difficulty pinning down this bit of trivia: What was the name of the secret society that kept pestering him to be a member?
“The Mystic Order of the Koo-koo Mama Hotcha Koo-koo Mama Hotcha Koo-koo Mama Hotcha,” as near as I can make out.
Good luck finding the spelling from an authoratative source, though.
That version also crops up on several Betty Boop sites.
Sounds like “Boom Boom a Hot Cha” to me. http://www.youtube.com/watch?v=RFrBG4xyaF8#t=0m43s
From the rhythm pattern in the orchestra before the singing starts, there might be another “a” between the “booms”.
“Hot Cha” was a phrase popular around that time. For example, see The Hot Cha Melody (1935) The Hot Cha Melody (Short 1935) - IMDb
