A little piece of trivia: When John Wayne first arrived in Hollywood, he learned cowboy mannerisms by watching... Wyatt Earp!
(This was around 1926. Earp was a movie consultant at the time.)
Yes. I knew because I am a lifelong John Wayne fan.
Just bought the EP by Runaway June, a trio that includes Jennifer Wayne, his granddaughter. From a side/front angle, I can see she looks like a female version of him from that young, lean age, Tom Mix era and before.
Wild West invokes her granddad in the refrain.
