This short was released the same year as 'My Favorite Blonde' starring Bob Hope and Madeline Carroll. That's probably the reason for the title.
The background art is less detailed and more abstract in this short, which is unusual for animation from this era.
Porky is singing "On Moonlight Bay," a song from 1912 by the American Quartet. It was made into a feature film less than a decade after this cartoon premiered.
One of the few times Daffy is actually shown flying. Well, he is a duck, after all!
Daffy wears a coonskin cap, a popular fad of the era. It would be worn in films and on TV by actors portraying the Western adventurers Davey Crockett and Daniel Boone, and by children who wanted to emulate those heroes.
