I need help. I know the riff is not Funkadelic's "What is Soul," I know the riff is not Band of Gypsys' "Machine Gun," but I know the riff. I was drunk at my neighbor's one night and he was playing some live recording of this and I was like, "yeah man, Chili Peppers did this, it's called What is Soul," and he thought I was nuts. http://www.youtube.com/watch?v=kldWAZPU8TA
SO what is the riff from?
