Shield (tinfoil or aluminum foil as some call it) is for noise. You might get lucky. Not too long ago, the foil didn't exist and things still worked.
Forgot to mention:
The inside of the foil is conductive. The bare wire will contact the tinfoil most of the lenth of the wire except where it is broken. If you made good splices, you should be fine.
