Query: For a good cause

I just purchased this single and like it. Part of the proceeds are also going to the WTC Tragedy which is my main reason for purchasing it. I remember the original recording and it is just as good, only with a lot more voices. However, the back of the CD jewel box APPEARS to indicate that there is a vocal version at 3:59 minutes, and an instrumental version at 3:59 minutes. There is no instrumental version, just the vocals.
