Unheard Version of Classic James Brown Song

Came across this last night on youtube (well my boyfriend was the one actually looking for the studio version of the song) and I have to say I was blown away by this variation of James Brown’s probably most popular song. This is the definition of funk, IMO.
I Got You (I Feel Good)

I think many James Brown fans are aware of this version, but casual fans are not. It is mind-blowingly good, though.
