i have the doggystyle album and it does have g'z up ho'z down, its verry old. ive heard only the first 10 or 100k have it. cd's that got altered that i know of (actually almost every cd gets different released differently for the producer or the artist dont feel some cuts or whatever) are, Thug Life (this one got it bad) and not to mantion the chronic. i really like to hear the song mr officer. friend of mine has this old source magazine (with the famous pic of dre with black cap holding a revolver to his head) from 92 where they interview snopp dre and some of the pound (before any of them blew up, offcourse snoop and dre had it going on cause of 187um) (notice how suge is behind somebody everytime in the pics not to get noticed) dre was letting the interviewer hear the ablumwhen he mentions this song. all the songs in the interview + some extras got released on the cd but not mr officer. dre was even singin the hook in the interview going like: mr officer mr officer, i wanna c u layin in a coffin sir. guess it was too hot to be released back then, still wouldnt mind hearing it now since the before 97 deathrow era has the best music to offer for me.
