I had never heard Joseph Williams had worked on the prequels. So for example, "The Street Singer" on TPM would be his work? Is he completely uncredited? The TPM Ultimate Edition doesn't mention him, and I never caught his name on any film credits. Did he ever do work on Indiana Jones as well?
Someday maybe I'll commission or talk someone into "re-creating" the Max Rebo tracks for me, for fun. I have no musical talent myself (other than as a lyricist, but that doesn't really count), but I know a couple of people who could pull it off if they just had the right equipment (one of which might already, I'll have to ask him).
As for Lapti Nek, the film version you made is so good, that I think I can be satisfied for the rest of my life with that if nothing better ever comes along. Also, thank you for finding what I always called the "Lapti Nek 12" Single" versions. I had never been able to dig that up.
