Lyrics:

I don't need no, I don't need no slackDon't you do it, it'll stop you in your tracksYou might think it's clever, not enough foreverBut a monkey on your backAin't no future, the late night ain't the wayIf you got problems, face them now todayCos there ain't no use in hidin', but you'll watch your girlfriends dyin'The monkey makes you payTell'emYou might think I ain't got no place to preachBut paradise is right there in your reachBut I'm here to tell ya, heroin's gonna kill yaThe monkey's just a leech
