The Dark Crystal Cast and Crew List

[skekKot]

Does anyone know of a full cast & crew listing for THE DARK CRYSTAL , that lists STEVE WHITMIRE as performing the character (Ydra the Podling) ? I found a listing(address+phone# London 1982) of Dark Crystal performers; and it has
Steve Whitmire performing PODMA {YDRA}

I can't find any other listing online, that lists him performing that character
