The first released version only had Puffy & The Lox on it (from the aforementioned DJ Clue mixtape), a second version was also recorded with Lil Kim & Biggie on the original beat. Then for one reason or another they decided 2 switch the beat up for Biggie's verse on the album version and call it the remix...
I'm not entirely sure if Biggie & Kim recorded their verses at the same time as Puffy and the Lox, but they were definately meant for that song...
