Who sang the "Have Gun - Will Travel" theme?

What video?

This song makes me think of the movie Stand By Me.

I met Johnny Western when he was staying at the home of actor Ben Johnson along with another young singer named Johnny Cash. I always remembered that the version of the song he sang was much longer than what was heard on the TV show. This is part of a story much too long for this space.

Player #272443, who is Johnny western? l never heard of him. but l do remember the song and program
