Denny Laine's Instagram post about the anniversary of the album's release notes that "I Don't Mind" is a James Brown song. I hadn't known this before. It turns out that I actually had Brown's version in my collection, but I hadn't listened to it yet. When I did, I discovered that this feature isn't present there; it's specific to the Moodies' version. (This line isn't even in Brown's version.) It's worth noting, though, that Brown does this same thing in his "Bewildered" (from the same year as "I Don't Mind" - 1961), although there he emphasizes the third syllable.
