I know I downloaded those but I can't find 'em. the readme sez:

In the case of 'Freebies' (officially sanctioned Sixus1 free downloads) you have the right to use them in commercial (for profit) work, but not redistribute the original files, altered or not without permission; except in the case of 3rd party copy right holders (as in Jabba the Hutt, Yoda, The Violator, Spawn, etc......) then they may be for personal use only.

another guy did yoda, but he recently lost his mum and sis, hence now is not a good time.
the obvious thing would be to IM rebekah.
