You most likely do have them all. In fact, When they first came out, i only bought BJ and 7800 cause to me those were the rarest tracks out of all of them. Of the rest of them only the "I Believe" from the Count Basie show in 92 on KTF was the ONLY track I didnt have on CD, I had it on a 45. IF you are an avid "Import Single" collector then you most likely have them all, other than the bonuses on the first two albums....
