Leo Gordon
Just browsed the cast list and saw no listing for him.
IMDB lists those who made at least two guest appearances so if he guested at all it would only have been for a single episode.
Would like to have seen him and Hugh tangle like Leo did against Cheyenne in that series.
Even though choreographed it was still good entertainment.
Just browsed his IMDB entries.
He did just one episode of Wyatt Earp called "When the Shooting Starts".
Would like to have seen more.
