yeah kottonmouth joined pko later he was listed as an official member of PKO on his album cover but i'm not sure i ever heard him on a pko album, but on the no pain no gain album it looks like Kottonmouth on cover. Haven't listened to it in years. Pony J changed his name to Nino, Originally it was Pony j, K-Sam and magic mark, and C-Lo was there sometime later and maybe a couple others in the mix.
