(I know what you mean) Just mixing up beginning word sounds with others. Like "Rindercela" (Cinderella)
Archie Campbell on He Haw started the whole thing. Some of my favorites are "tig bitties" and "nard hipples"
Heard some other versions too on Music You Can't hear on the Radio. Don't know who did that one.
Lyrics were like this, so maybe a studio verion of Jack Ross? Cinderella and her Sisty Uglers
