three versions.. the live squad one i have never heard of. freddie said in his own voice that he did the track with benzino, then he cut benzino and put pac on it. im not sure if thats exactly what he said cause i'll have to check but i think pac and benzino were never on the same track. there was some beef with benzino if i remember correctly. so technically, there are two versions of the track. "dont fuck with a killah" with freddie foxx and tupac, and "dont fuck with a killah" with freddie foxx and benzino. if there is one with the live squad pac must have re-recorded it at a later date, alternatively he had already recorded the verse and re-recorded it when he was with freddie foxx. either way i'd like to see a source lol.
