[iTunes] Help save the orphans in iTunes

[Scott Replogle]

Long story short:
Moving 100 GB of song files to a different location and upgrading to  
Leopard and migrating a previous iTunes library results in massive  
numbers of orphaned music files -- too many to fix individually.
I'm looking for an app or script to find orphans in iTunes and  
repatriate them with their physical song files (without starting over,  
losing present iTunes playlists, and without duplicating everything by  
importing the moved folder of song files).

Any known solutions?

Thanks,
