Yes, it will. I have this problem sometimes. When you forward it, you will see friend 1's email address in the body of the text (where you can write something in your own email) - just delete the correspondence and address section from the friend, leaving the attachments fror friend 2 to see.
If you get asked for an option, forward the email "in-line" rather than "as attachment".
That may work but I'd do a test and check that the information isn't still available to anyone who selects the option of viewing the headers as that may show the full path
