I listened to The Magnificent Moodies yester-day and noticed a plethora of things about which I'll have posts for the next week or so (although almost all of them are just small points).
In the third "You know I feel alright" at the beginning of "I'll Go Crazy," the "al-" of "alright" is sung with a melisma spanning an octave: F Eb C Bb Ab F. Musically, this gives a sense of entirety.
I'm not sure of the specific notes, but "much" in the line "Oh, love you too much" is also sung with a melisma, musically giving a sense of amount or degree. This is also present in James Brown's original (although Brown's melismas are just two notes [C Bb] where the Moodies have many more).
