Movie I remember watching on tv

Ok, the opening scene as I remember: some guy playing a tune with a guitar (one could only see his hand playing). The music is also the opening song.

Out of the blue he gets shot and falls from the top of a small…hill?

I watched this on tv, I think it was late 70’s.

It’s definitely Gunman Called Nebraska, a.k.a. Ringo from Nebraska,

Thank you so much buddy.:+1: After all this years.
