That's the subtitle font, alright! Nice goin Rosco! Unfortunately I can't find a free download of it anywhere; it's a commercial font. I did find two or three with identical names to Cezanne, but that's all the two had in common. The sites you listed all have links back to font.com which only sells fonts; no freebies. Every search I've run only comes up with the commercial joints. But that's definitely it!
The cowboy font lowercase looks quite a bit like the lowercase of Cezanne. The two share a general style anyway. If you want to take this to e-mail, mine is delta6 at bigfoot dot com.
Edit: Found the cowboy font! It's called Texas Hero.
Texas Hero I also found a similar font called Letter 1882. Cezanne can, supposedly, be had as Poison the Well. Unfortunately I haven't been able to track it down.
