Just found this in a "Colorado ODDities" website and thought it'd be interesting to see if anyone knows it:

One of the few original cowboy songs with Colorado roots revolves around the story of what happened to Robert Ford when he fled after murdering Jesse James in 1882. Here's the first verse of A Song about Robert Ford :

Gather round friends and a story I'll tell
Of a man named Bob Ford; it's one you know well
He shot Jesse James in cold-blooded greed
Come out to stay in the boom town of Creede.

Here's a little more of interest from the same website:

Bat Masterson once owned a saloon in Creede Colorado, high in the San Juan Mountains in Mineral County. And Bob Ford, the man who shot Jesse James, was killed in Creede. It happened when Ed O'Kelly, the marshal of nearby Bachelor, came into town, said he was a friend of the James brothers, then shot Ford -- owner of a bar and brothel -- in the face.

Thanks!
