I checked the files here on the two official Ringo films and they say there's an English audio track re. the Koch releases. But it's very good to know that they each have English subs.
The file for Ringo and His Golden Pistol/Johnny Oro says the only DVDs are the Italian and Japanese ones. It also says the only audio track is Italian in both cases. But does anyone know if there are optional English subs on either of them?
