John Wayne was one of the first "singing cowboys" in films (predating the popularity of Gene Autry and Roy Rogers)... using
the same method but with the clip of Everybody Loves Somebody Sometime that is posted above exhibiting what most would find
better vocal skill...
A collection of Wayne's career as a singing cowboy can be
seen and heard here. Wayne recounts the history of his singing career in
this chat with Dean Martin (at 3:40) and at the end of the clip contributes to the performance of a classic.
