The first 6 songs were all recorded by Bonnie Tyler. You can probably find a compilation album with them all on.
Tonight Is What It Means To Be Young was on the soundtrack to the film Streets Of Fire and was recorded by Fire Inc. It was then reworked into Dance Of The Vampires for the musical Tanz Der Vampire.

What Part Of My Body, Not Allowed To Love and Still The Children were from the aborted Batman musical I think.
