I would like to find the title of a cowboy song from way back,possibly by either Burl Ives or Marty Robbins.I was only a boy when I used to hear this played by my older brother.I am talking 50s/60s here.

Now here comes the hard part.All I remember is that who ever was killed by the cowboy,over the grave grew a bush/tree forming the letter T .This pointed to the killer name.

I await with fingers crossed.
