I’d love to see ‘Deaf Smith…’ released on bluray.
The trailer doesn’t do it justice…the narration sounds like it’s done by someone with nothing better to do…
I’ve only seen it once, on Youtube, about 8 years ago. It was crap quality, but I thoroughly enjoyed it at the time. I remember the interaction between Franco Nero and Anthony Quinn being rather wonderful. After all, we are talking about two distinguished actors at their peak…
When I last viewed it, the magic of the inspired pairing shone through.
The main theme was, and still is, extremely memorable…whether you pick the vocal or instrumental version - both, IMHO - are brilliant. To my mind, it’s a ‘feel good’ theme, and a great way to start the day. 
This ‘buddy’ film deserves better treatment than it has received on any format… 
Note: The ‘Deaf Smith and Johnny Ears’ theme is sung by Ann Reid Collin; who also sang the main theme to ‘Shoot the Living, Pray For the Dead’.
