The version I head off a 78 record my parents had went

Belle Star is a rider wild broncos she breaks
but she promised to quit it just for my sake
She ties up one foot and the saddle puts on
with a swing and a jump she is mounted and gone

last stanza

Now all you young cowboys where ere you beside
beware of the gal when she swings the rawhide
She'll court you and pet you the off she will go
on the trail anytime there's a bucking bronco.

I do not remember who sang it but I never knew there was a different version until I started looking for it lately. Now it looks like it was not the original at all.
