C-Bo feat. Cap'n Save'm "Still Riden" off'a Bay Area Playas 2. He disses P on that.
And no as far as I know of P never dissed back, C-Murder I guess dissed Yuk on his Trapped In Crime cd, on the song "Ride", he uses the I Got 5 On It beat. I haven't heard the song, I just heard around that it's a diss.
Snoop dissed Bo on that Lay Low song off'a The Last Meal "Bo-Loc betta watch what you say" or some shit like that, he says it in a low voice.
